How to Calculate Court Deadlines Under FRCP 6: Counting Days, Holidays, Backward Counts and the E-Service Myth

Fed. R. Civ. P. 6(a)(1) tells you how to calculate court deadlines in federal civil cases: exclude the day of the event that starts the clock, count every calendar day after it (weekends and holidays included), and include the last day. If the last day is a Saturday, Sunday, or legal holiday, the period runs to the next day that is none of those.

This guide covers federal civil practice. State courts have their own computation rules, usually similar but not identical. For one example, see our guide to Utah civil procedure deadlines.

FRCP Rule 6: the short version

FRCP 6(a)(1): counting forward

The rule has three moves. Exclude the day of the triggering event. Count every day, "including intermediate Saturdays, Sundays, and legal holidays." Include the last day, but if it falls on a Saturday, Sunday, or legal holiday, "the period continues to run until the end of the next day that is not a Saturday, Sunday, or legal holiday."

Worked example: a 21-day answer across a holiday weekend. A defendant is personally served with a summons and complaint on Friday, December 4, 2026. The answer is due "within 21 days after being served" under Rule 12(a)(1)(A)(i). Exclude December 4. Day 1 is Saturday, December 5. Day 21 is Friday, December 25, Christmas. The period continues to the next day that is not a weekend or legal holiday: Monday, December 28.

The same count with no holiday in the way (service on Tuesday, November 17) ends on Tuesday, December 8, with no rollover. For the answer itself, see how to answer a complaint.

Days are days since 2009

Before December 1, 2009, periods shorter than 11 days skipped weekends and holidays and longer ones did not. The 2009 amendments made every period stated in days count the same way. The committee note says many 10-day periods became 14-day periods "to compensate" for the change. Older treatises and some calculator sites still recite the pre-2009 method. If a guide tells you to skip weekends in a 7-day period, it is describing the rule as it stood before 2009.

FRCP 6(a)(5): counting backward

Some deadlines run before an event rather than after it. Rule 6(a)(5) says the "next day" is determined "by continuing to count forward when the period is measured after an event and backward when measured before an event."

Rule 6(a)(2), sometimes cited for this, governs periods stated in hours. Backward counting is 6(a)(5).

In a backward count, the weekend-or-holiday rollover moves the deadline earlier, not later. That is where lawyers who roll forward by habit lose a day.

Worked example: motion served 14 days before the hearing. Rule 6(c)(1) requires a written motion and notice of hearing to be served "at least 14 days before the time specified for the hearing," absent an exception. The hearing is Friday, January 8, 2027. Count back 14 days from the hearing date: December 25, a legal holiday. The deadline moves backward to the previous day that is not a weekend or holiday, Thursday, December 24. Serving on the 25th, or on Monday the 28th by mistake, is late.

One caution: Presidents closed federal agencies on December 24 by executive order in 2018, 2019, 2020, 2024 and 2025. If a 2026 order does the same and your court treats it as a holiday under Rule 6(a)(6)(B), the deadline moves back again, to Wednesday, December 23.

Worked example: opposing affidavits 7 days before. Under Rule 6(c)(2), any opposing affidavit must be served "at least 7 days before the hearing, unless the court permits service at another time." Seven days before January 8 is Friday, January 1, 2027, New Year's Day. Count backward: Thursday, December 31.

FRCP 6(a)(6): federal court legal holidays

The rule's definition has three parts:

Two details trip people up.

Juneteenth was added to the list by a 2023 amendment. A guide whose holiday list jumps from Memorial Day to Independence Day predates it.

State holidays count for forward counts only. A state-declared holiday can extend your 21-day answer period but cannot push back a backward-counted deadline, such as the 14 days before a hearing.

FRCP 6(a)(4): when the last day ends

Getting the day right does not settle the hour. Rule 6(a)(4) sets it: "Unless a different time is set by a statute, local rule, or court order, the last day ends: for electronic filing, at midnight in the court's time zone; and for filing by other means, when the clerk's office is scheduled to close."

So an e-filing is timely through 11:59 p.m. in the court's time zone, not the filer's. A California lawyer filing in a New York court is working against Eastern time.

The opening clause does real work. A local rule or court order, including a judge's standing order, can set an earlier cutoff, such as 5:00 p.m. A paper filing at the counter must beat the posted closing time. If the clerk's office is inaccessible on the last day, Rule 6(a)(3) extends the time to the first accessible day that is not a weekend or holiday, unless the court orders otherwise.

FRCP 6(d): the 3-day rule, and the e-service myth

Rule 6(d) reads: "When a party may or must act within a specified time after being served and service is made under Rule 5(b)(2)(C) (mail), (D) (leaving with the clerk), or (F) (other means consented to), 3 days are added after the period would otherwise expire under Rule 6(a)."

Look at what is missing. Electronic service under Rule 5(b)(2)(E) used to be on that list. The 2016 amendment removed it. The committee note explains that technology had reduced the transmission concerns behind the old rule, and that adding three days "complicated the counting." It adds that courts can still grant extensions where after-hours e-service causes prejudice. That is a request to the judge, not an automatic right.

Some calculators and guides still say e-service earns three extra days. That has been wrong since December 1, 2016.

Three more points:

• The days are added after the Rule 6(a) period would expire. Finish your Rule 6(a) count first, rollover included, then add three. If the third day is a Saturday, Sunday, or legal holiday, the deadline moves to the next day that is not, as the 2005 committee note explains.
• The rule applies only to periods that run from service. A deadline fixed by a hearing date or court order does not get the extra days.
• The extra days belong to the party who was served by mail (or by the other listed means), not to the party who did the serving.

Worked example: mail service. A party serves a motion by mail on Monday, November 2, 2026, and the rules give the other side 14 days after service. Exclude November 2. Day 14 is Monday, November 16. Add 3 days under Rule 6(d): Thursday, November 19. Had service been through the court's e-filing system, the response would be due November 16.

Requests for admission are one place it bites in practice: the response clock runs from service, so the method of service changes the date.

Where opposition deadlines come from

The Federal Rules set no general deadline for opposing a motion. Rule 6(c) covers the notice of hearing and opposing affidavits, not the opposition brief. The brief's deadline comes from the local rules of the district, the judge's standing order, or a scheduling order. It varies a great deal from one district to the next, and even from one judge to the next.

Where to look, in this order:

1. The scheduling order or any order setting a briefing schedule on the motion.
2. The assigned judge's standing orders or individual practices.
3. The district's local rules, usually under a rule numbered 7 in the civil section.
4. The Federal Rules, for the few motions with a built-in clock.

Rule 6 tells you how to count; the local rules tell you the number. Our table of federal motion response deadlines by district collects the local-rule answers. For the substance of the response, see how to respond to a motion to dismiss and how to oppose a motion for summary judgment.

FRCP 6(b): extensions, and the clocks that cannot move

Some clocks cannot be extended. Rule 6(b)(2) provides that a court "must not extend the time to act under Rules 50(b) and (d), 52(b), 59(b), (d), and (e), and 60(b)." If you are counting toward one of those, see our guide to the motion for reconsideration. Other deadlines set by the Rules or a court order can be extended for good cause under Rule 6(b)(1), but you should ask before the deadline passes, not after. A motion made after it must also show excusable neglect.

How to calculate court deadlines: a checklist

1. Identify the trigger: service, entry of an order, a hearing date. Write down the date.
2. Identify the rule that sets the period, and whether it runs after or before the trigger.
3. Check for a local rule, standing order, or scheduling order that sets a different period or a different cutoff time.
4. Count forward or backward, excluding the trigger day.
5. If you land on a weekend or legal holiday, roll in the direction of the count. Apply state holidays only to forward counts.
6. If service was by mail, with the clerk, or by consented other means, add three days after step 5. If the third day is a weekend or legal holiday, roll forward again.
7. Put the earliest defensible date on the calendar, not the latest.
8. Have a second person recount it.

Frequently asked questions

How do you calculate a deadline in federal court?

Under Rule 6(a)(1), exclude the day of the triggering event, count every day including weekends and holidays, and include the last day. If the last day is a Saturday, Sunday, or legal holiday, the period runs to the next day that is none of those. Periods counted before an event run backward instead.

Does electronic service add 3 days to a deadline?

No. Since the December 2016 amendment, Rule 6(d) adds three days only when service was made by mail, by leaving the paper with the clerk, or by other means the recipient consented to in writing. Service through the court's electronic filing system, or by consented electronic means, no longer adds time.

Do weekends and holidays count in a federal deadline?

Yes, in the middle of a period. Since 2009 every day counts, however short the period. Weekends and legal holidays matter only on the last day: if the period ends on one, it continues to the next day that is not a Saturday, Sunday, or legal holiday, or the previous such day when counting backward.

What time is a federal filing due on the last day?

Unless a statute, local rule, or court order sets a different time, an electronic filing is due by midnight in the court's time zone. A filing by other means is due when the clerk's office is scheduled to close. A local rule or court order, including a judge's standing order, can set an earlier cutoff, so check before relying on midnight.

Do state holidays count when computing federal court deadlines?

Only for periods measured after an event. Rule 6(a)(6)(C) treats a holiday declared by the state where the district court sits as a legal holiday for forward counts. It does not apply to periods measured before an event, such as the 14 days before a hearing.

Where CaseRead fits

Counting is yours to do. When CaseRead pulls dates from an order or notice for the matter calendar, it computes none: it adds the dates the document actually states once you confirm them, and flags periods written as "within N days" so you know to run the count above and enter the date yourself.

A deadline often comes with a brief to write. Before it goes out, run the draft through the Hallucination Shield. It is free, needs no signup, and checks up to 50 citations per run, flagging any it cannot verify.
