Court Date Calculator and Legal Deadline Calculator
Enter the event that starts the clock and how many days the rule gives you. This court date calculator applies Federal Rule of Civil Procedure 6(a): it drops the trigger day, counts every weekend and holiday in between, and rolls a deadline that lands on a weekend or federal legal holiday to the next business day.
- Counts forward from an event or backward to a hearing
- Knows all eleven federal legal holidays, with the observed-day shift
- Shows its work so you can verify every count

This tool applies the federal method in FRCP Rule 6(a). State courts, court-day rules, and local standing orders can differ. Always confirm against the governing rule.

How to calculate a court filing deadline
Under Federal Rule of Civil Procedure 6(a), you exclude the day of the triggering event, then count every day after it, including intermediate Saturdays, Sundays, and legal holidays. You include the last day of the period. If that last day is a Saturday, Sunday, or legal holiday, the deadline continues to run until the end of the next day that is not one of those.
-
Step 1
Find the trigger
Identify the exact day the clock starts: service, entry of an order, or filing. That day itself is not counted.
-
Step 2
Count every day
Count each calendar day after the trigger, weekends and holidays included, until you reach the number the rule gives you.
-
Step 3
Check the last day
If the last day is a Saturday, Sunday, or federal legal holiday, roll the deadline forward to the next business day.
-
Step 4
Confirm the local rule
Verify against the statute, local rule, or standing order that governs your matter. Some deadlines run in court days, not calendar days.
A worked example
Say you are served with a complaint in federal court and have 21 days to answer under Rule 12(a)(1)(A)(i). Service happened on Friday, July 3, 2026.
You exclude July 3, the day of service. Day one is Saturday, July 4 (Independence Day is a holiday, but intervening holidays still count toward the total). You keep counting every day. The twenty-first day is Friday, July 24, 2026, which is a business day, so the answer is due Friday, July 24.
Now change the facts: suppose the count had landed on Saturday, July 25. Because the last day cannot be a weekend, the deadline would roll to Monday, July 27. Enter these dates in the calculator above and you will see the same result, with the roll shown explicitly.
Federal legal holidays the calculator applies
FRCP Rule 6(a)(6) defines a legal holiday as any day set aside by federal statute for observance. When a fixed-date holiday falls on a Saturday it is observed the Friday before, and when it falls on a Sunday it is observed the following Monday. The calculator uses the observed day.
| Holiday | When it falls |
|---|---|
| New Year's Day | January 1 |
| Martin Luther King Jr. Day | Third Monday in January |
| Washington's Birthday | Third Monday in February |
| Memorial Day | Last Monday in May |
| Juneteenth | June 19 |
| Independence Day | July 4 |
| Labor Day | First Monday in September |
| Columbus Day | Second Monday in October |
| Veterans Day | November 11 |
| Thanksgiving Day | Fourth Thursday in November |
| Christmas Day | December 25 |
The President or Congress can declare additional holidays, and for deadlines measured after an event, a state holiday where the district court sits also counts. Confirm any unusual closure against your court's calendar.
Questions people ask about counting court deadlines
How do you calculate days for legal deadlines?
Exclude the day of the triggering event, then count every day after it, including weekends and holidays, until you reach the number of days the rule gives you. Include the last day. If the last day is a weekend or legal holiday, move the deadline to the next business day. That is the FRCP Rule 6(a) method this calculator uses.
Do you count weekends for court deadlines?
Yes, for periods stated in days you count every intervening Saturday and Sunday toward the total. Weekends only change the outcome when the final day lands on one, in which case the deadline rolls forward. Older rules excluded weekends for short periods, but that has not been the federal method since the 2009 amendments.
What if a court deadline falls on a weekend?
If the last day of the period is a Saturday, Sunday, or legal holiday, the period continues to run until the end of the next day that is not one of those. For a deadline counted backward from a hearing or trial, the rule works in reverse: it moves to the prior business day.
What is the difference between calendar days and court days?
Calendar days count every day on the calendar; court days count only days the clerk's office is open, skipping weekends and holidays as you count. Federal deadlines in days are calendar days under Rule 6(a)(1). Some state rules, like California's short notice periods, run in court days, so read the governing rule before you count.
How do you calculate court deadlines in California?
California runs many of its notice periods in court days rather than calendar days, which is the single most common counting mistake lawyers make when they move between federal and state practice. Under Code of Civil Procedure section 1005(b), moving papers are served at least 16 court days before the hearing, opposition at least 9 court days before, and reply at least 5 court days before. Electronic service adds extra days under section 1010.6. Always count from the governing statute for your specific motion rather than from a general rule.
How many days do you have to respond to a complaint in federal court?
Twenty one days after service of the summons and complaint, under Federal Rule of Civil Procedure 12(a)(1)(A)(i). If the defendant waives service under Rule 4(d), the period becomes 60 days from the date the waiver request was sent, or 90 days if the defendant is outside any judicial district of the United States. The United States and its agencies get 60 days. Count the days on the calendar, then roll forward under Rule 6(a)(1)(C) if the last day is a weekend or legal holiday.
Is this a court date calculator for state courts too?
The calculator above counts under Federal Rule of Civil Procedure 6(a), which is the right method for federal filings and for the many states that have adopted the same counting structure. It is not a substitute for your state's rules where those differ, and several states do differ in ways that change the answer: court day counting, different holiday schedules, and extra days added for the method of service. Use it as a first pass, then confirm against the governing rule and your local rules before you calendar anything.
How do you build a civil procedure timeline for a case?
Work forward from the triggering events rather than backward from trial. Each service date, filing, order and hearing creates its own set of downstream dates, so record the trigger, the governing rule and the computed date together for every deadline. The reason firms miss dates is rarely the arithmetic; it is that a new order arrives, nobody recalculates what it changed, and the timeline silently goes stale. That recalculation on every incoming document is what deadline tracking software is for.
A calculator counts one deadline. An agent tracks every deadline in the file.
Caseagent reads new filings, extracts the dates that create obligations, and keeps a live deadline timeline for each matter, with escalating reminders. The count above is a starting point; the agent is what stops a missed date.
