Frequently Asked Questions

How is a court deadline calculated? ▼

Under Federal Rule of Civil Procedure 6(a), you exclude the day of the triggering event itself, then count every following calendar day — including weekends and holidays — toward the deadline. If the final day lands on a Saturday, Sunday, or legal holiday, the deadline moves to the next business day.

Does this add the 3 extra days for mail service? ▼

Optionally — FRCP Rule 6(d) adds 3 days after the Rule 6(a) deadline when the document was served by mail, by leaving it with the court clerk, or by other means the person consented to. Since the December 1, 2016 amendment, electronic service through the court's system no longer gets the extra 3 days. Check the box if this applies to your situation.

Does this apply to state courts too? ▼

Most state court systems use a similar calendar-day counting method with a weekend/holiday extension, but the exact rules, deadline lengths, and observed holidays can differ by state and by court. This calculator uses the federal (FRCP) rule and federal holidays — always confirm against your specific court's local rules and the applicable statute or order before relying on the result.

Is this legal advice? ▼

No — this is a date-math tool based on the general federal computation-of-time rule. It doesn't account for court-specific local rules, judge's standing orders, or substantive law governing what deadline applies to your case. Confirm any real deadline with an attorney or the court clerk.

How long do I have to answer a federal complaint? ▼

Under FRCP 12(a)(1)(A), a defendant generally has 21 days to answer after being personally served with the summons and complaint, or 60 days (90 days if outside the US) if they waived formal service. The presets on this calculator auto-fill these common periods — always confirm which applies to your specific case.

How federal court deadlines are counted

Federal Rule of Civil Procedure 6(a) sets the method for deadlines stated in days:

Exclude the day of the event that triggers the period, such as the day you were served.
Count every day after it, including weekends and legal holidays.
Include the last day, but if it falls on a Saturday, Sunday or legal holiday, the period runs to the end of the next day that is not one of those.

If you were served by mail, by leaving the document with the court clerk, or by another method you consented to, Rule 6(d) adds 3 days after the period would otherwise end under Rule 6(a). Electronic filing through the court's system no longer gets those 3 days since the 2016 amendment.

Examples

A 30-day period triggered on Monday, October 12, 2026 would end on Wednesday, November 11. That is Veterans Day, so the deadline becomes Thursday, November 12.
A 21-day answer period after personal service on Friday, October 2, 2026 ends on Friday, October 23.

Common federal civil deadlines

Deadline	Days	Rule
Answer after personal service	21	FRCP 12(a)(1)(A)(i)
Answer after waiver of service (in the US)	60	FRCP 12(a)(1)(A)(ii)
Response to an amended pleading	14	FRCP 15(a)(3)
Notice of appeal in most civil cases	30	FRAP 4(a)(1)(A)
Notice of appeal when the US is a party	60	FRAP 4(a)(1)(B)

Federal legal holidays used

New Year's Day, Martin Luther King Jr. Day, Washington's Birthday, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving and Christmas, moved to the observed weekday when they fall on a weekend. Rule 6 also treats days the clerk's office is inaccessible, and any day declared a holiday by the President or Congress, as excluded.

Important limits

State courts, criminal cases, bankruptcy and many agencies have their own rules, and local rules or a judge's order can change a deadline. Always confirm with the court's rules or an attorney; a missed deadline can be fatal to a case.
