Trigger day
The first question is whether the day of the event counts. Many court-style rules exclude the day of the triggering event and start counting on the next day.

What This Deadline Calculator Does Differently
Most deadline calculators stop at "add 14 days" or "skip weekends." That is not enough for real deadlines. Legal, court, agency, customer-support, shipping, and finance deadlines often depend on the trigger date, whether the first day counts, whether intermediate weekends count, whether the final day moves, which holidays apply, what happens after a cut-off time, and whether service adds extra time.
This page separates those choices instead of hiding them. You can model a calendar-day deadline where only the last day is adjusted, a court-day style deadline where closed days are never counted, a business-day deadline with custom company closures, or an SLA deadline that counts only open business hours.
Common Deadline Rules To Check
Intermediate closed days
Some rules count every calendar day and only adjust the final date. Other rules count only business or court days, so weekends and holidays inside the period never count.
Final-day adjustment
If the calculated last day lands on a weekend, holiday, or closed day, many rules move the deadline to the next open day. Some backward-counted deadlines move in the opposite direction.
Service extensions
Some legal and administrative deadlines add extra days for particular service methods. The calculator can add a service or grace extension after the base period, but you must verify the exact rule.
Cut-off time
A document received after a daily cut-off may count as received on the next open day. SLA deadlines also need business-hour windows, not just dates.
Local time zone
The time zone selector labels the local court, office, or filing-system time used for the deadline. It does not convert the deadline into other time zones.
Holiday source
Federal, state, local, court, bank, carrier, and company calendars can differ. Use the preset holiday list as a starting point and add local closures manually.
Legal and Court Deadline Caution
This tool is for calculation support, not legal advice. Court orders, procedural rules, local rules, agency rules, electronic filing rules, clerk-office closures, and emergency orders can change the result.
For an actual filing, verify the governing rule, local rule, judge order, service method, holiday calendar, and filing system cut-off before relying on a date. When the consequence matters, calendar the deadline independently and have another person check the calculation.
FAQ
Is a deadline calculator the same as a date duration calculator?
No. A duration calculator tells you how much time is between two dates. A deadline calculator starts with a trigger event and applies a rule to find the due date.
What is a court day?
A court day is usually a day when the relevant court is open for filing or business. Weekends and court holidays are normally excluded, but the exact definition depends on the court and rule.
Why does the audit table matter?
Deadlines are easy to dispute when the result is just a date. The audit table shows each counted or skipped day, the reason, and whether the final date was moved.
Can I calculate backward from a hearing or event?
Yes. Change the direction to backward. This is useful for notice periods, prep deadlines, publication windows, and dates that must happen a certain number of days before an event.
