Answer Deadline Calculator: Answer to Complaint Deadline and Response Due Date, by Court

Enter the date the summons and complaint were served and get the date the responsive pleading is due, with the right base period, the service method applied, and the last day rolled forward if the court is closed. Federal, California, Texas and Florida, each rule cited so you can check the count by hand.

Handles the Texas Monday next rule, which no plain day counter gets right
Substituted service, waiver of service, removal and government defendants
Shows every step of the count, on four separate statutory holiday lists

Counting something other than a responsive pleading? The court deadline calculator handles calendar day periods generally, the court days calculator handles periods a rule states in court days, and the discovery deadline calculator handles responses to interrogatories, production requests and admissions. If what you need is the outer deadline to bring the case at all rather than a date inside it, use the statute of limitations calculator. For any other federal period, from the Rule 4(m) service deadline through the post trial motions and the notice of appeal, the federal court deadline calculator takes the FRCP event by name.

Court and rules

How the defendant got the case

The day of service is not counted. Counting starts the next day.

Local rules, standing orders and written stipulations routinely change these periods, and a defective proof of service can move the start date. Confirm any computed date against the governing rule before you calendar it.

The short answer

A defendant served with a summons and complaint has 21 days to answer in federal court, 30 days in California, and 20 days in Florida. Texas does not use a day count at all. Under Rule 99(b) the answer is due at 10:00 a.m. on the Monday next after 20 days run, which lands anywhere from 21 to 28 calendar days after service depending on the weekday. Two things move these dates more often than practitioners expect: when service is legally complete, which in California substituted service is the 10th day after the mailing rather than the day the papers were left, and the roll forward when the last day is a weekend or a court holiday, which happens on roughly a third of all service dates.

August 2026

Every rule below was read against its primary text, including the 2021 version of Texas Rule 99 and the January 2025 amendment to California Code of Civil Procedure 1167. Every date range was computed over every service date rather than estimated, and the calculator was checked against a second independent implementation across 39,447 cases.

Exhibit A Start here

How long a defendant has to answer, by court

Each of these is the period for an ordinary private defendant served in the ordinary way. Everything that changes it is attached to a specific posture, not to the type of claim.

Court	Answer due	Rule	Real calendar span	Government defendant
Federal	21 days after service	FRCP 12(a)(1)(A)(i)	21 to 24 days	60 days after service on the U.S. attorney, 12(a)(2)
California	30 days after the summons is served	CCP 412.20(a)(3)	30 to 34 days	No general extension; check the claims statute
Texas, district and county	10:00 a.m. the Monday next after 20 days	TRCP 99(b)	21 to 28 days	Same rule; sovereign immunity is a separate question
Texas, justice court	End of the 14th day after service	TRCP 502.5(d)	14 to 18 days	Service by publication moves it to 42 days after issuance
Florida	20 days after service of process and the initial pleading	Fla. R. Civ. P. 1.140(a)(1)	20 to 26 days	40 days, 1.140(a)(2)(A); 30 days for a section 768.28 claim

Florida's 20 days is the shortest period in this table, and it is the one lawyers who mostly practice in federal court or in California undercount. It is also the only one of the four that is almost never 20 days on the calendar, because Rule 2.514(a)(1)(A) does not begin the count on the day after service. It begins on the first day after service that is not a Saturday, Sunday or legal holiday, so a complaint served on a Friday has its day one on the following Monday. That is why the real answer date lands between 20 and 26 days out. Do not look for a service extension to save you either: Rule 2.514(b) adds 5 days for service by mail, but that provision applies to service of papers under Rule 1.080, not to service of original process, which is what starts the answer clock.

Exhibit B Rule 99(b)

The Texas Monday rule, which is the one people get wrong

Texas is the only one of these four that pins the answer to a weekday instead of a day count. The citation itself carries the language, so the defendant is told the rule but not how to apply it.

"The citation shall direct the defendant to file a written answer to the plaintiff's petition on or before 10:00 a.m. on the Monday next after the expiration of twenty days after the date of service thereof."

Tex. R. Civ. P. 99(b), 2021 text

Count 20 days from the day after service. Then go to the first Monday that comes after that day. The word doing the work is "next after the expiration of." Day 20 does not expire until it ends, so when day 20 is itself a Monday, the answer is not due that morning. It is due the Monday of the following week. That reading was settled in Proctor v. Green, 673 S.W.2d 390, 392 (Tex. App. Houston [1st Dist.] 1984, orig. proceeding), and it is the single most common Texas answer date error.

Day 20 falls on a Monday whenever the defendant was served on a Tuesday. So Tuesday service is the case to slow down for. Everything else follows the plain reading. If the resulting Monday is a Texas legal holiday, Rule 4 pushes the answer to the next day that is not a Saturday, Sunday or legal holiday, which is what produces the 28 day maximum. In 2026 that catches five Mondays: January 19, February 16, March 2, May 25 and September 7.

Served on a	Day 20 is a	Days to answer
Monday	Sunday	21
Tuesday	Monday	27
Wednesday	Tuesday	26
Thursday	Wednesday	25
Friday	Thursday	24
Saturday	Friday	23
Sunday	Saturday	22

Add one more day when the resulting Monday is a Texas legal holiday. Texas observes 15 statutory holidays and, unlike the federal and California lists, applies no weekend shift, so a Texas holiday that lands on a Saturday simply passes.

Exhibit C California, mostly

When service is legally complete, which is what actually starts the clock

California measures the 30 days from when service is complete, and for four of the six service methods that is not the day the papers changed hands. Getting this wrong in the plaintiff's favor means moving for a default that is not yet available.

Method	Statute	Service is complete	Response due, counting from the act
Personal delivery	CCP 415.10	On delivery	30 days after delivery
Substituted service, leave and mail	CCP 415.20(a) and (b)	On the 10th day after the mailing	40 days after the mailing
Mail with notice and acknowledgment	CCP 415.30(c)	On the date the acknowledgment is executed	30 days after that date, not after the mailing
Mail with return receipt, defendant outside California	CCP 415.40	On the 10th day after the mailing	40 days after the mailing
Publication	CCP 415.50(c), Gov. Code 6064	At the end of the 28th day, counting the first publication day	30 days after that
Unlawful detainer, any method	CCP 1167(a) and (b)	Same as above by method	10 court days, plus 5 more court days if served by mail

The unlawful detainer row is new enough that most of what you will find online is wrong. Assembly Bill 2347 amended section 1167 effective January 1, 2025 and replaced the old five calendar day response period with 10 days that exclude Saturdays, Sundays and judicial holidays. In practice that is 12 to 19 calendar days rather than five to seven, and it changes the whole rhythm of an eviction. Serving a tenant on a Friday buys the tenant more time than serving on a Monday: 10 court days from Friday June 4, 2027 is Monday June 21, while from Monday June 7 it is Tuesday June 22, only one day later for three extra days of delay.

Exhibit D Worked through

One service date, nine different answer dates

A summons and complaint served on Friday, September 3, 2027. Same defendant, same day, same proof of service. Only the forum and the posture change.

Forum and posture	Answer due	Days	Why
Texas, justice court	Fri Sep 17, 2027	14	End of the 14th day, and it is a business day
California, unlawful detainer	Mon Sep 20, 2027	17	10 court days, stepping over two weekends and Labor Day
Florida, private defendant	Mon Sep 27, 2027	24	Day one is Tue Sep 7 because Labor Day follows the weekend, then day 20 is Sun Sep 26
Federal, personal service	Fri Sep 24, 2027	21	Rule 12(a)(1)(A)(i), lands on a Friday
Texas, district court	Mon Sep 27, 2027	24	Day 20 is Thursday Sep 23, so the Monday next after is Sep 27
Federal, removed on Sep 20	Mon Sep 27, 2027	24	7 days after the notice beats the 21 day date by three days
California, personal service	Mon Oct 4, 2027	31	Day 30 is Sunday Oct 3, which rolls to Monday
California, substituted service	Wed Oct 13, 2027	40	Service completes Sep 13, then 30 days runs from there
Florida, state agency	Mon Oct 18, 2027	45	Rule 1.140(a)(2)(A) doubles the period, counted from the same Tue Sep 7 day one

Thirty-one days separate the first row from the last, and none of that spread comes from anything a lawyer chose. It comes from the forum, the entity being sued and the envelope the process server used. The federal removal row is the one worth studying: a defendant removed on Monday September 20 gets Monday September 27, three days later than the 21 day federal date, because Rule 81(c)(2) takes the longest of the three periods. Remove on Wednesday September 8 instead and the seven day period ends September 15, the 21 day period still controls, and the answer stays due Friday September 24. Removal buys time only when it happens late.

Exhibit E Three steps, in order

How to calculate an answer deadline by hand

Do these in sequence. Reversing steps two and three is how a date ends up a day early or a day late.

01

Fix the date service was complete

Not the date the complaint was filed and not the date the defendant first heard about it. For personal delivery that is the delivery date. For California substituted service it is the 10th day after the mailing. Read the proof of service, not the cover email.

02

Count the base period

Start the day after service and count every day, weekends and holidays included. Federal 21, California 30. In Texas count 20 and then move to the Monday next after that day. Florida is 20 but its day one is the first day after service that is not a weekend or a legal holiday, Rule 2.514(a)(1)(A). In a California unlawful detainer count 10 court days instead, skipping closed days as you go.

03

Roll the last day forward

If the last day is a Saturday, Sunday or a legal holiday in that forum, the period runs to the next day that is not. FRCP 6(a)(1)(C), CCP 12a(a), TRCP 4 and Fla. R. Gen. Prac. 2.514(a)(1)(C) all say the same thing. Use the right holiday list: the four do not match.

04

Check the posture last

Removal, a waiver of service, a government defendant, a pending Rule 12 motion or a stipulated extension each override the ordinary count. Any one of them replaces the whole calculation rather than adjusting it, so confirm none applies before you calendar the date.

The roll forward in step three is not an edge case. Across every service date from 2020 through 2035, the raw last day lands on a weekend or a court holiday 31.6 percent of the time in federal court and 32.4 percent in California. Roughly one answer date in three is not the date a plain day count gives you. In Florida it is 59.3 percent, because Rule 2.514(a)(1)(A) pushes day one onto a Monday for every complaint served on a Friday, Saturday or Sunday, and 20 days from a Monday always lands on a Saturday.

Exhibit F Both directions

What happens when the answer date passes

Miss it as a defendant and you are exposed to a default. Move on it too early as a plaintiff and you have a defective default that the other side can undo cheaply.

Court	How a default is taken	Getting out of it
Federal	Clerk enters default under Rule 55(a), then judgment under Rule 55(b)	Entry of default set aside for good cause, Rule 55(c). A default judgment needs Rule 60(b)
California	Request for entry of default, CCP 585. Rule of Court 3.110(g) requires it within 10 days after the response was due	CCP 473(b), six month outer limit, mandatory relief on an attorney affidavit of fault
Texas	Default judgment after the Monday deadline passes with no answer on file	Motion for new trial under the Craddock standard, or a restricted appeal
Florida	Clerk's default under Rule 1.500(a), or court default under 1.500(b)	Rule 1.500(d) sets aside a default; Rule 1.540(b) for a judgment

One practical point for defendants: an answer filed a day late but before anyone requests a default is usually just accepted. In federal court there is nothing to set aside until the clerk enters default, and in California a response filed before the request for entry is processed generally stands. The worst thing to do with a missed date is wait. File the responsive pleading, then deal with the consequence.

For plaintiffs the risk runs the other way, and it is mostly a California problem. If you request entry of default on day 31 after substituted service, the defendant's 30 days had not even started, because service was not complete until the 10th day after the mailing. That default is vulnerable, and the motion to vacate it is cheap for the defendant and expensive for you. Compute from completion of service, and read the proof of service before you file the request.

Exhibit G What comes next

The clocks that start once the answer is on file

The answer date is the first of a run of dates that follow from it. These are the ones that matter in the first ninety days of a case.

Amending as of course

Federal Rule 15(a)(1) gives 21 days after serving a pleading, or 21 days after service of a responsive pleading or a Rule 12(b), (e) or (f) motion, whichever is earlier. Miss it and you need consent or leave.

Texas initial disclosures

The 2021 amendment to Rule 99(c) puts the warning in the citation itself: disclosures are generally due no later than 30 days after the defendant files its answer. The answer date sets that date.

The Rule 26(f) conference

At least 21 days before the scheduling conference or the Rule 16(b) order, which itself is due the earlier of 90 days after any defendant is served or 60 days after any defendant appears.

Written discovery responses

Thirty days in all four jurisdictions, with service extensions that differ. The discovery deadline calculator handles those, including the California two court day e-service rule.

California case management conference

Rule of Court 3.722 sets it no later than 180 days after the complaint is filed, and Rule 3.110(b) requires service on all defendants within 60 days of filing.

Serving the complaint at all

Federal Rule 4(m) gives 90 days after filing, and the court must dismiss without prejudice if the plaintiff cannot show good cause. That clock runs before any answer clock starts.

Answer deadline questions, answered from the rule text

How many days do you have to answer a complaint?

Twenty-one days in federal court under Rule 12(a)(1)(A)(i), 30 days in California under Code of Civil Procedure 412.20(a)(3), and 20 days in Florida under Rule 1.140(a)(1). Texas does not use a fixed day count at all: the answer is due at 10:00 a.m. on the Monday next after 20 days run, which works out to between 21 and 28 calendar days. The clock starts the day after service, not the day the complaint was filed.

What is the deadline to answer a complaint in Texas?

By 10:00 a.m. on the Monday next after the expiration of 20 days after the date of service, under Texas Rule of Civil Procedure 99(b). Count 20 days from service, then move to the first Monday after that day. If day 20 is itself a Monday the answer is due the following Monday, per Proctor v. Green, 673 S.W.2d 390, 392. Justice court is different: 14 days under Rule 502.5(d).

How long do you have to respond to a complaint in California?

Thirty days after the summons is served, under Code of Civil Procedure section 412.20(a)(3). The trap is when service is deemed complete. Substituted service under section 415.20 is complete on the 10th day after the mailing, so the response is really due 40 days after the papers were left and mailed. Out of state mail with return receipt under 415.40 works the same way.

How many days to answer a complaint in federal court?

Twenty-one days after being served with the summons and complaint. Rule 12(a)(1)(A)(i). A defendant who returns a waiver of service under Rule 4(d) gets 60 days from the date the request was sent, or 90 days if it was sent outside any judicial district of the United States. The United States and its agencies and officers get 60 days after service on the United States attorney.

What is the deadline to answer a complaint after removal?

The longest of three periods under Rule 81(c)(2): 21 days after receiving the initial pleading, 21 days after service of the summons, or 7 days after the notice of removal is filed. A defendant removed on day 19 of the state clock therefore does not get a fresh 21 days. It gets whichever of those three dates falls last, which is usually the original 21 day date.

What happens if you miss the deadline to answer a complaint?

The plaintiff can take a default. In federal court that is a two step process: the clerk enters default under Rule 55(a), then the court enters judgment under Rule 55(b). Entry of default can be set aside for good cause under Rule 55(c), which is a far easier standard than vacating an entered default judgment, so filing late is still better than not filing.

Does the day of service count when calculating an answer deadline?

No. Every one of these jurisdictions excludes it. Federal Rule 6(a)(1)(A) excludes the day of the event that triggers the period, California Code of Civil Procedure 12 excludes the first day and includes the last, and Texas Rule 4 excludes the day of the act or event. Florida goes further than the other three: Rule 2.514(a)(1)(A) does not start the count until the first day after service that is not a Saturday, Sunday or legal holiday, so service on a Friday puts day one on Monday.

What happens if the answer deadline falls on a weekend or a holiday?

It rolls forward to the next day the court is open. This is not a rare event: across every service date in 2027, the raw last day lands on a weekend or a legal holiday about 32 percent of the time in federal court and 33 percent of the time in California. The holiday lists differ, so the same complaint served the same day can produce different dates in different forums.

How many days to respond to an unlawful detainer in California?

Ten days, excluding Saturdays, Sundays and judicial holidays, under Code of Civil Procedure 1167(a) as amended by AB 2347 effective January 1, 2025. It used to be five calendar days and a great deal of published material still says so. Service by mail or through the Secretary of State address confidentiality program adds five more court days under section 1167(b).

Can you get an extension of time to answer a complaint?

Usually yes, and usually by agreement. Federal Rule 6(b)(1)(A) lets the court extend the period for good cause on a motion made before the time expires, and most districts let the parties stipulate to a first extension without leave. In California, Rule of Court 3.110(d) contemplates a stipulated extension of up to 15 days beyond the 30 day period. Get it in writing and file it.

CASE FILE

The answer date is only as good as the proof of service it came from

One new matter is a two minute count. Thirty new matters a month, each with its own service method and its own forum, is where a date goes in wrong and nobody notices for three weeks. Caseagent puts an AI agent inside the case file, so the document that starts the clock is the same thing that sets the date.
