Why this page does not calculate a date
The operative deadline is the EARLIER of this forward date and the backward 7-days-before-argument date in us_fed_appellate_xa_appellee_reply_before_argument_7.
Read FRAP 28.1"the appellee's reply brief, within 21 days after the appellant's response and reply brief is served, but at least 7 days before argument unless the court, for good cause, allows a later filing"
Fed. R. App. P. 28.1(f)(4)
Which date starts the 21-day period?
The period runs from the service of the appellant's response and reply brief.
Count forward from the trigger event. Confirm the event on the docket or in the service record before entering a date.
Read FRAP 28.1"the appellee's reply brief, within 21 days after the appellant's response and reply brief is served, but at least 7 days before argument unless the court, for good cause, allows a later filing"
Fed. R. App. P. 28.1(f)(4)
This period runs from service as the rule defines it. Do not substitute the filing date, the day a courtesy copy arrived or the day you first read the paper.
Which date do I enter?How are the 21 calendar days counted?
- Exclude the day of the trigger event.
- Count every following day, including intermediate Saturdays, Sundays and legal holidays.
- If the last day is a Saturday, Sunday or legal holiday, continue to the next day that is not one of those.
Exclude the trigger day and count calendar days under FRAP 26(a).
If the final day is a Saturday, Sunday or legal holiday, FRAP 26(a) carries it to the next open day.
FRAP 26(a) also treats a day on which the clerk’s office is inaccessible as excluded from the last day, and sets the electronic filing cutoff at midnight in the time zone of the circuit clerk’s principal office. Circuit local rules and briefing orders often control; the national calculation does not read them.
Read FRAP 26(a)The calculation gives the ordinary national-rule date. Check relevant holidays, the court’s accessibility and its filing cutoff separately.

Common questions
Find answers about when this 21-day period starts, how it is counted, what can change it and how to keep your calculation.
Starting the clock
Does the clock start on the service of the appellant's response and reply brief, or when I first learned of it?
The period runs from the service of the appellant's response and reply brief as the rule defines it, not from the day you read about it, received a courtesy copy or attended a hearing. Use the date shown on the docket or in the service record.
Read FRAP 28.1Do I add three days because the paper was served by mail?
FRAP 26(c) adds three days only after the listed non-electronic methods of service, such as mail. Electronic service through the court’s filing system does not add days. Check how service was actually made before adding anything.
FRAP 26(c)Counting days and filing
Is it 21 calendar days or business days?
Calendar days. Count intermediate weekends and holidays. If the final day is a Saturday, Sunday or legal holiday, FRAP 26(a) carries it forward to the next day that is not one of those.
FRAP 26(a)Which time zone and filing cutoff apply?
Under FRAP 26(a)(4), electronic filing ends at midnight in the time zone of the circuit clerk’s principal office unless a different time is set. Paper filing ends when the clerk’s office is scheduled to close. This calculator does not verify either fact.
FRAP 26(a)What if the court is inaccessible on the last day?
FRAP 26(a)(3) extends the period to the first accessible day that is not a weekend or legal holiday when the clerk’s office is inaccessible on the last day. Check the circuit’s closure notices and orders.
FRAP 26(a)Extensions and local rules
Can the court extend this deadline?
Extendable for good cause under FRAP 26(b), subject to the 7-day-before-argument backstop. A request does not itself extend the period, and no discretionary extension is calculated here.
Read FRAP 28.1Do local rules, standing orders or a scheduling order change the date?
They can. Many courts set their own periods by local rule, standing order or case-specific order, and those control over the national default. This calculator gives the national-rule date only; compare it with any order in the case before relying on it.
Choosing the right calculator
Does this calculator decide whether the rule applies to my case?
No. It calculates a period from the date you provide under the cited rule. It does not decide whether the rule governs your filing, whether an exception applies, or whether the filing has merit. Those questions need separate review.
Can I calculate the deadline without an account?
Yes. Enter the trigger date to see the free national-rule calculation, citation, counting steps and warnings. You can add court context after the result. Missing court review keeps the result provisional.
Results, records and your case
What is included in an Evidence Record?
The retained inputs, result, cited rule, calculation working, warnings and review state. The PDF includes a payload digest and retained-data appendix, and the record can be verified against its fingerprint later. It records the calculation, not a guarantee of legal correctness.
Does saving to a case activate the calendar?
Not automatically. Provisional records remain subject to review. A separately labeled manual date does not alter the original calculation.
