A court day is a day the courts are open for business — generally excluding weekends and public holidays. Exactly which days count, and whether calendar days or court days apply to a given deadline, is set by the procedural rules of the specific jurisdiction and case type.

Court Day Calculator: Count Court Days From Any Date (Free)

Q: Does this calculator know my state's deadline rules?

No. This tool performs general court-day math only — it counts a number of court days forward from a date, skipping weekends and U.S. federal holidays. It does not apply any state-specific statute, local rule, or named deadline type. Always verify the applicable rule and count method in your jurisdiction before relying on a date.

Q: Does it count weekends and holidays?

It skips weekends (Saturday and Sunday) and U.S. federal holidays when counting court days forward. It does not account for state-specific court holidays or local closures, which vary by jurisdiction.

This is a general calculation aid, not legal advice. It counts calendar days forward or backward, skipping Saturdays, Sundays, and U.S. federal holidays. It does not apply any state statute, local court rule, or named deadline type (such as a specific discovery or filing deadline), and it does not account for state-specific court holidays. Court-day rules and what counts as a "court day" vary by jurisdiction and case type — always verify against your local rules of court or rules of civil procedure before relying on a date.

The Hammer Lex's deadline engine generates a full case's downstream deadlines from a single trigger date, applying the jurisdiction rule set you choose — not just a single date, and not manual math.

How court-day counting works

Many procedural deadlines are measured in "court days" or "business days" rather than straight calendar days — meaning weekends, and sometimes holidays, don't count toward the total. Other deadlines are measured in plain calendar days, where every day counts including weekends. Which method applies, how the trigger date itself is treated (does day one start on the trigger date or the day after?), and which holidays are observed are all questions answered by the specific procedural rule for that deadline — not by a general formula.

This calculator performs the underlying arithmetic only: start from a date, count a number of days forward or backward, skip weekends and U.S. federal holidays. It is a starting point for sanity-checking a date, not a substitute for reading the rule that actually governs your deadline.
