Texas Court Deadline Calculator and Answer Deadline Calculator
In a Texas district or county court the answer is due by 10:00 a.m. on the Monday next after the expiration of twenty days after service, under Rule 99(b). That is never a flat twenty days. Depending on the weekday you were served and the holidays in the way, the real deadline lands between twenty-one and twenty-nine days out. Enter the date below and this calculator applies Rule 99(b), Rule 4 and the Texas legal holidays for you.
- The Monday rule, including the week you gain when day twenty is itself a Monday

How the Texas Monday rule actually works
Texas is the only large state that ties the answer date to a day of the week. Rule 99(c) puts the language on the face of every citation: a written answer is due "by 10:00 a.m. on the Monday next following the expiration of twenty days after you were served this citation and petition." Read literally, that is a two step calculation, and the second step is where people go wrong.
-
Step 1
Drop the day of service
Rule 4 excludes the day of the act or event that starts the clock. If you were served on a Wednesday, the count begins Thursday.
-
Step 2
Count twenty calendar days
Twenty is more than five, so every day counts. Weekends and legal holidays inside the window do not extend anything. Mark the twentieth day.
-
Step 3
Move to the next Monday
Find the first Monday that falls after the twentieth day. If day twenty is itself a Monday, the period has not expired until that evening, so you take the Monday after it.
-
Step 4
Roll a holiday Monday forward
Five of the fifteen Texas legal holidays always land on a Monday. When the answer Monday is one of them, Rule 4 pushes the deadline to Tuesday.
The trap worth remembering
Being served one day later can push the answer date a full week later, because a single day can move the twentieth day across a Monday. Service on Monday, August 10, 2026 produces an answer date of Monday, August 31. Service on Tuesday, August 11, one day later, produces Tuesday, September 8. That is an eight day swing from a one day difference, and it is the most common miscalculation in Texas default judgment practice.
A worked example, and the one day that costs a week
Every date below was computed with the rules above and checked twice. Enter the service dates in the calculator and you will get the same answers.
| Date of service | Twentieth day | Answer due (10:00 a.m.) | Days from service | Why |
|---|---|---|---|---|
| Wednesday, August 5, 2026 | Tuesday, August 25 | Monday, August 31 | 26 | The first Monday after day twenty. |
| Monday, August 10, 2026 | Sunday, August 30 | Monday, August 31 | 21 | Day twenty is a Sunday, so the very next day is the answer Monday. This is the shortest the rule ever gets. |
| Tuesday, August 11, 2026 | Monday, August 31 | Tuesday, September 8 | 28 | Day twenty is a Monday, so the deadline is the following Monday, September 7. That is Labor Day, so Rule 4 rolls it to Tuesday. |
| Thursday, November 5, 2026 | Wednesday, November 25 | Monday, November 30 | 25 | Thanksgiving and the Friday after it are legal holidays, but they fall inside the twenty day window, where every day counts anyway. |
| Tuesday, December 1, 2026 | Monday, December 21 | Monday, December 28 | 27 | Day twenty is a Monday again. December 25 is a legal holiday, but December 28 is not, so no further roll. |
The shortest possible Texas answer period is twenty-one days, which happens when service lands on a Monday and no holiday interferes. The longest runs to twenty-nine. A defendant served on Tuesday, December 22, 2026 reaches day twenty on Monday, January 11, 2027, which pushes the answer to Monday, January 18. That is Martin Luther King, Jr., Day, and January 19 is Confederate Heroes Day, so two consecutive legal holidays carry the deadline to Wednesday, January 20, 2027. Anyone who calendars "twenty days from service" is wrong every single time, usually in the defendant's favor, which is exactly why plaintiffs lose default judgments on appeal.
Texas civil deadlines at a glance
Texas states almost every civil period in calendar days, then modifies the count with Rule 4. The direction of the count is what changes: answer and disclosure dates run forward from an event, while summary judgment and expert dates run backward from a hearing or from the end of the discovery period.
| Deadline | Period | Counted from | Direction | Authority |
|---|---|---|---|---|
| Answer, district or county court | 20 days, then the next Monday, 10:00 a.m. | Date of service | Forward | TRCP 99(b) |
| Answer, justice court | 14 days | Date of service | Forward | TRCP 502.5(d) |
| Answer after service by publication | 42 days | Date the citation issued | Forward | TRCP 502.5(e) |
| Initial disclosures | 30 days | Filing of the first answer or general appearance | Forward | TRCP 194.2(a) |
| Summary judgment motion and affidavits | At least 21 days | The hearing | Backward | TRCP 166a(c) |
| Summary judgment response | Not later than 7 days | The hearing | Backward | TRCP 166a(c) |
| Expert designation, party seeking relief | 90 days | End of the discovery period | Backward | TRCP 195.2(a) |
| Expert designation, all other experts | 60 days | End of the discovery period | Backward | TRCP 195.2(b) |
| Motion for new trial | Within 30 days | The day the judgment was signed | Forward | TRCP 329b(a) |
Rule 190 discovery control plans change the end of the discovery period, which in turn moves both expert deadlines. A Level 1 or Level 3 case will not match the Level 2 defaults, so read the scheduling order before you calendar an expert date.
Rule 4's five day rule, and the result that looks like a mistake
This is the Texas provision that surprises lawyers from other states. Rule 4 says that "Saturdays, Sundays, and legal holidays shall not be counted for any purpose in any time period of five days or less." There is no separate concept of a "court day" in Texas as there is in California. Instead, the same calendar day counts or does not count depending purely on how long the period is.
A five day period beats a six day period
Start both on Friday, November 20, 2026, the Friday before Thanksgiving week.
The five day period skips the weekends, Thanksgiving on November 26 and the Friday after it, so the days are November 23, 24, 25, 30 and December 1. It ends Tuesday, December 1.
The six day period counts every day, landing on Thanksgiving itself, then rolls forward past the holiday and the weekend. It ends Monday, November 30.
The longer deadline arrives first. That is not a bug in the calculator, it is what Rule 4 says, and it is a good reason to check short deadlines against a calendar rather than intuition.
| Period length | Weekends and holidays | What Rule 4 does |
|---|---|---|
| 5 days or less | Not counted at all | Skipped as you count, so the period always ends on an open day |
| More than 5 days | Counted normally | Only the last day is adjusted, rolling forward if it is a weekend or legal holiday |
| The 3 day mail extension | Counted | Rule 4 carves this out expressly, so the three days include weekends and holidays |
Justice courts do not follow this rule at all. Rule 500.5(a)(2) tells you to count every day including Saturdays, Sundays and legal holidays, with no five day carve out, and then adds an extension Rule 4 does not have: if the court closes before 5:00 p.m. on the last day, the period runs to the next business day.
What gets three extra days in Texas, and what gets nothing
Rule 21a(c) is short and narrow: "Whenever a party has the right or is required to do some act within a prescribed period after the service of a notice or other paper upon him and the notice or paper is served upon him by mail, three days shall be added to the prescribed period." Mail is the only trigger. Texas removed the fax extension, and it never added one for electronic service, even though e-service through the electronic filing manager is now mandatory for represented parties.
| Method of service | Days added | Notes |
|---|---|---|
| 3 | The only method Rule 21a(c) extends. Service is complete on deposit in the mail, not on receipt. | |
| Electronic, through the filing manager | 0 | Complete on transmission to the filing service provider. No extension in Texas, unlike California, which adds two court days. |
| In person | 0 | Complete on delivery. |
| Commercial delivery service | 0 | Complete on deposit with the service. Rule 21a(c) names only mail, so no three days. |
| Fax | 0 | Complete on receipt, and deemed served the next day if completed after 5:00 p.m. The old three day fax extension was removed. |
| The citation itself | 0 | Rule 21a(a) expressly excludes the citation served on filing of the suit, so the answer deadline is never extended by the method of service. |
The last row is the one that matters most. Lawyers who cut their teeth in federal court sometimes add three days to a Texas answer deadline because the defendant was served by certified mail. Rule 21a(a) takes the citation out of the rule entirely, so there is nothing to extend. The Monday rule is already the whole cushion.
Texas legal holidays the calculator applies
Rule 4 uses the phrase "legal holiday" without defining it. The definition lives in Government Code section 662.021, which is narrower than most people assume: a legal holiday is one of the nine national holidays in section 662.003(a) plus the first six state holidays in section 662.003(b). Fifteen days in total.
| Legal holiday | Date in 2026 | Source |
|---|---|---|
| New Year's Day | Thursday, January 1 | National, 662.003(a)(1) |
| Martin Luther King, Jr., Day | Monday, January 19 | National, 662.003(a)(2) |
| Confederate Heroes Day | Monday, January 19 | State, 662.003(b)(1) |
| Presidents' Day | Monday, February 16 | National, 662.003(a)(3) |
| Texas Independence Day | Monday, March 2 | State, 662.003(b)(2) |
| San Jacinto Day | Tuesday, April 21 | State, 662.003(b)(3) |
| Memorial Day | Monday, May 25 | National, 662.003(a)(4) |
| Emancipation Day in Texas | Friday, June 19 | State, 662.003(b)(4) |
| Independence Day | Saturday, July 4 | National, 662.003(a)(5) |
| Lyndon Baines Johnson Day | Thursday, August 27 | State, 662.003(b)(5) |
| Labor Day | Monday, September 7 | National, 662.003(a)(6) |
| Veterans Day | Wednesday, November 11 | National, 662.003(a)(7) |
| Thanksgiving Day | Thursday, November 26 | National, 662.003(a)(8) |
| Friday after Thanksgiving | Friday, November 27 | State, 662.003(b)(6) |
| Christmas Day | Friday, December 25 | National, 662.003(a)(9) |
December 24 and 26 are not legal holidays
They are state holidays under section 662.003(b)(7) and (b)(8), so state offices close, but section 662.021 stops at subsection (b)(6). For Rule 4 counting they are ordinary days. This catches people every December.
Two holidays collide in 2026
Martin Luther King, Jr., Day is the third Monday in January, which is January 19 in 2026, the same fixed date as Confederate Heroes Day. Fifteen statutory holidays therefore produce only fourteen distinct dates next year, and one of those, July 4, falls on a Saturday.
There is no observed day shift
Section 662.003 fixes these holidays to actual dates. Nothing in it moves a Saturday holiday to the preceding Friday the way federal practice does, so this calculator does not shift them either.
A limit worth knowing about
Rule 4 extends a deadline only for a Saturday, Sunday or legal holiday. Unlike the justice court rule, and unlike Rule 4.1(a) of the appellate rules, it contains no clause for a clerk's office that happens to be closed on the last day. County clerks close for local reasons, for the days around Christmas, and for weather. If your deadline lands on one of those days, Rule 4 does not move it on its own, and you should file early rather than argue about it later.
Texas counting compared with federal and California
Firms with a multi-state docket calendar the same event three different ways. The unit, the direction and the extension rules all differ, and none of the three is a safe default for the others.
| Question | Texas (TRCP) | Federal (FRCP) | California (CCP) |
|---|---|---|---|
| Time to answer a complaint | 10:00 a.m. the Monday after 20 days | 21 days after service | 30 days after service |
| Are short periods counted differently? | Yes, 5 days or less skips weekends and holidays | No, every period counts all days since 2009 | Yes, court day periods skip all closures |
| Extension for service by mail | 3 days | 3 days | 5 days in state, 10 elsewhere in the US |
| Extension for electronic service | None | None | 2 court days |
| Motion notice period | Set by local rule, 21 days for summary judgment | 14 days for most responses | 16 court days before the hearing |
| Holidays that do not count | 15 statutory legal holidays | 11 federal holidays | 14 judicial holidays |
| Last day on a closed clerk office | Not covered by Rule 4 | Extended under FRCP 6(a)(3) | Extended under CCP 12a |
A case removed from a Texas state court to a federal district court changes clocks mid-stream. Removal does not revive an expired answer deadline, but it does put the rest of the schedule under FRCP 6 and the district's local rules, so re-derive every downstream date rather than shifting the old ones.
Five ways Texas deadlines get miscalculated
These are the errors that show up in motions to set aside default judgments and in malpractice claims over blown deadlines. Every one of them comes from applying a sensible general rule that Texas happens not to follow.
Calendaring twenty days from service
The answer is never due twenty days after service. The shortest real period is twenty-one days and the longest is twenty-eight. A defendant who files on day twenty-one when the true date was day twenty-eight has done no harm, but a plaintiff who takes a default on day twenty-one has an unenforceable judgment.
Taking the Monday that day twenty falls on
When the twentieth day is itself a Monday, the twenty day period has not expired until that Monday ends. The answer Monday is the one after it, a full week later. This single mistake produces most premature defaults.
Adding three days for e-service
Rule 21a(c) adds three days for mail only. Electronic service, which is mandatory for represented parties, adds nothing in Texas. California adds two court days for e-service, which is where the habit usually comes from.
Adding three days to the answer date
Rule 21a(a) expressly excludes the citation from the rule, so no method of serving the citation extends the answer deadline. Certified mail service does not buy the defendant three extra days.
Treating a short period like a long one
A period of five days or less skips weekends and legal holidays entirely. Counting five calendar days instead of five countable days will usually put you several days early, which is safe, but it also means a six day period can fall due before a five day one across a holiday week.
Assuming justice court works the same way
It does not. Rule 502.5(d) gives fourteen days with no Monday rule, and Rule 500.5 counts every calendar day with no five day carve out but adds a closure extension Rule 4 lacks. An eviction or debt claim docket runs on a different clock than the district court down the hall.
Questions people ask about Texas court deadlines
How many days do you have to answer a lawsuit in Texas?
In a Texas district or county court the answer is due by 10:00 a.m. on the Monday next after the expiration of twenty days after the date of service, under Rule 99(b). That is not a flat twenty days. Depending on which weekday you were served and the legal holidays in the way, the real deadline falls between twenty-one and twenty-nine days after service.
How do you calculate the Texas answer deadline?
Exclude the day you were served, because Rule 4 does not count the triggering day. Count twenty calendar days forward, including weekends and holidays. Then move to the first Monday that comes after that twentieth day. If that Monday is a legal holiday, the deadline rolls to the next day that is not a Saturday, Sunday or legal holiday.
What happens if the 20th day falls on a Monday in Texas?
You get the following Monday, not that one. Rule 99(b) sets the deadline at the Monday next after the twenty day period expires, and the period does not expire until the end of the twentieth day. So a Monday twentieth day pushes the answer date a full week out, giving the defendant twenty-seven days rather than twenty.
Do you count weekends in Texas court deadlines?
It depends on the length of the period. Rule 4 says Saturdays, Sundays and legal holidays are not counted for any purpose in a period of five days or less. In any period longer than five days every calendar day counts, and only the last day is adjusted if it lands on a weekend or legal holiday.
Do you get 3 extra days for service by mail in Texas?
Only for service by mail. Rule 21a(c) adds three days when a paper is served by mail, and Rule 4 says weekends and holidays are counted inside that three day window. Electronic service through the electronic filing manager gets no extension in Texas, and neither does the citation, which Rule 21a expressly excludes.
What are the Texas legal holidays for court deadlines?
Government Code section 662.021 counts fifteen days: the nine national holidays in section 662.003(a) plus the first six state holidays in section 662.003(b), which are Confederate Heroes Day, Texas Independence Day, San Jacinto Day, Emancipation Day in Texas, Lyndon Baines Johnson Day and the Friday after Thanksgiving. December 24 and 26 are state holidays but not legal holidays.
How long do you have to answer in justice court in Texas?
Rule 502.5(d) gives a justice court defendant until the end of the fourteenth day after the day of service. There is no Monday rule in justice court. If the fourteenth day is a Saturday, Sunday or legal holiday the answer is due the next day that is not, and if the court closes before 5:00 p.m. that day it moves to the next business day.
When is a summary judgment response due in Texas?
Under Rule 166a(c) the adverse party may file and serve a response no later than seven days before the day of the hearing, except on leave of court. The motion itself and any supporting affidavits must be filed and served at least twenty-one days before the hearing. Both periods are counted backward from the hearing date.
What happens if you miss the answer deadline in Texas?
The plaintiff can move for a default judgment, but only after the deadline has actually passed. Filing an answer any time before the default is signed cuts it off, because Rule 121 makes an answer an appearance. A defendant who was served but never answered can also seek a new trial under the Craddock standard, and a defendant who was never properly served has stronger grounds still.
When are initial disclosures due in Texas?
Rule 194.2(a) requires initial disclosures within thirty days after the filing of the first answer or general appearance, unless the parties agree otherwise or the court orders a different date. A party served or joined later has thirty days from being served or joined. The citation itself now warns defendants that this obligation is coming.
One answer date is easy. Two hundred of them is a system problem.
A calculator answers one question at a time. Caseagent keeps the whole docket: it reads the citation and the scheduling order, calendars every dependent date under the right rule set, and tells you what moved when a hearing moves.
