Free Deadline & Date Calculators
Counting days is simple; the conventions are not
Four date tools that apply the convention you specify rather than assuming one: calendar or business days, inclusive or exclusive of the trigger day, rolled off weekends or not, with the court closures you supply.
Deadline Calculator
Count a deadline forward or backward from a trigger date in calendar or business days, with weekend and closure handling.

This tool performs arithmetic on the values you enter. It does not provide legal advice and does not create an attorney-client relationship.
Counting rules differ by court and jurisdiction, including whether the trigger day counts, how weekends and holidays are treated, and how a deadline that lands on a closure day is rolled. Always verify against the governing rule and the court calendar.

Every deadline count involves at least four choices, and each of them changes the answer. Does the triggering day count? Are the days calendar days or business days? Does a weekend result roll forward? Which days is the court actually closed?
These tools ask rather than assume, because the conventions differ between jurisdictions and even between rules within one. What they will not do is tell you which convention applies to your filing - that comes from the governing rule, and it must be verified.

Why use LegalDeadlineTools
Conventions made explicit
Trigger-day inclusion, count type and rolling behaviour are all choices you make, and the tool shows both the unadjusted and the adjusted date.
Closures you supply
Court holiday schedules differ by court and by year. Entering them is slower than a built-in list and considerably more reliable.
Backwards scheduling
Working back from a hearing date reveals immediately whether there is enough working time - eight weeks out, when something can still be done about it.
No account, nothing stored
Dates are entered and calculated in your browser. Nothing about your matters is transmitted or saved.
How it works
- Identify the governing rule and what convention it uses before calculating anything.
- Enter the trigger date, the count and the convention.
- Add the court closures that fall in the period.
- Verify the result against the rule and the court calendar - always.
Frequently asked questions
Can I rely on these dates for a court filing?
No. These tools count days exactly as instructed. They do not interpret court rules, do not know your jurisdiction, and have no court calendar. Every result must be verified against the governing rule.
Why do I have to enter court holidays?
Because they differ by court and change every year. A built-in list would be wrong more often than right, and being wrong about a closure is exactly how a deadline is missed.
Does the trigger day count?
It depends on the rule. Many procedural rules exclude the day of the act and include the last day; others do the opposite. That is why it is an option rather than a built-in assumption.
Is this legal advice?
No. This website provides general informational and productivity tools. It does not provide legal advice and does not create an attorney-client relationship.
Do these replace a docketing system?
No. Practice-wide deadline management needs rule-based calculation and independent verification. These are planning tools for individual dates.
