Court Date Calculator

Court deadlines are counted, not guessed — and the counting method decides the date. This planning aid adds a period to a trigger date two ways: simple calendar days, or “court days” that skip weekends and US federal holidays. A clear warning applies: counting rules differ between federal and state courts, so always verify against the rules governing your case.

Results

Assumptions: Planning aid only, not legal advice. Federal holiday list covers 2026–2028 (with observed dates for weekend holidays). Local court holidays and rule-specific adjustments are not included.

Formula

Both methods exclude the trigger day itself and start counting the next day:
Deadline = Trigger date + Period (by the chosen counting rule)
Court-day mode also skips the federal holiday calendar.

How to use this calculator

  1. Enter the trigger date (the event that starts the clock, such as service or an order).
  2. Enter the number of days in the period from the rule or order.
  3. Choose the counting method your court uses, then Calculate — and verify with the official rules.

Worked example

A 14-court-day period starting Monday, November 2, 2026.

  1. Counting from November 3, skipping weekends plus Veterans Day (Nov 11) and Thanksgiving (Nov 26 falls outside).
  2. The 14th court day lands on November 23.

Result: Estimated deadline: Monday, November 23, 2026.

Frequently asked questions

Do federal courts count weekends?

Usually yes. Since 2009, Federal Rule of Civil Procedure 6(a) counts every calendar day for most periods — weekends and holidays included — extending the deadline only if the final day is a weekend or federal holiday. The “court days” mode here matches other counting systems (such as many state rules for short periods).

What if the deadline lands on a weekend or holiday?

Under most rule systems the deadline rolls forward to the next business day. The calendar mode of this calculator does not apply that roll — check the raw result against the calendar.

Can I rely on this for a real filing?

No. Treat it as a planning estimate. Deadlines can also be changed by court orders, local rules, and the method of service (which sometimes adds days). Confirm with the governing rules or an attorney.
