# Federal Court Deadline Calculator

Published and updated 2026-10-04 · RuleX editorial team · United States · American English

Calculate a federal civil deadline by excluding the triggering day, counting every intermediate calendar day and adjusting the last day under Rule 6(a). Rule 6(d) adds three days after the adjusted period for specified types of service. Enter the period from the governing rule or order, then add applicable state holidays and court closure dates.

## Start with the rule that creates the deadline.

A deadline requires both a triggering event and a period. Record the filing, service, entry or other event that the governing provision actually uses. A scheduling order may supply a specific date or alter a period. Keep that order with the matter before using a day-count calculator.

This calculator handles periods measured forward in days in a federal civil matter. The result displays the triggering date, initial last day, adjustment and final date so you can review the calculation.

1. Identify the governing rule, statute or court order.
2. Enter the triggering date and the number of calendar days.
3. Select the service extension only when Rule 6(d) applies.
4. Add relevant state holidays and inaccessible-clerk dates.
5. Save the calculation alongside the order and calendar the reviewed deadline.

## Count intermediate weekends; adjust the final day.

For a period stated in days, Rule 6(a)(1) excludes the event day and counts the days that follow. A Saturday, Sunday or holiday inside the period remains in the count. When the last day is a weekend or legal holiday, continue to the next qualifying day.

Example: a 21-day period triggered on October 5, 2026 initially ends October 26, 2026. The intervening weekends remain part of the period. A court closure or applicable additional legal holiday on the final day changes the adjustment, which you can enter above.

## Apply three additional days at the right stage.

Rule 6(d) applies to obligations that run from service using the methods specified in Rule 5(b)(2)(C), (D) or (F). First determine when the original period expires under Rule 6(a), then add three days and adjust the resulting last day when required. Select the regular calculation for electronic service.

Identify the actual service method in the proof of service. A period triggered by entry of an order rather than service requires its own analysis of the governing provision.

## Calendar the filing time in the court’s time zone.

Rule 6(a)(4) generally places the electronic filing cutoff at midnight in the court’s time zone. For another filing method, use the clerk’s scheduled closing time. A statute, local rule or court order can set a different time. Record the cutoff and the time zone next to the date.

The holiday calendar displays standard federal observed dates. Select those closures in the calculator after checking that the court adopts them, or enter the specific closure dates. Review the district’s official calendar and orders. Rule 6(a)(6) also addresses relevant state holidays for forward-counted periods and holidays declared by the President or Congress. Add those dates to the calculation.
