Statute of Limitations Deadline Calculator
Enter the incident or discovery date and the limitation period that applies to your claim to estimate the filing deadline and how many days are left.
Filing deadline
How the deadline is calculated
The calculator takes your start date — the discovery date if you provide one, otherwise the incident date — and adds the limitation period you enter, applying the years first, then the months, then the days. Month math clamps to the end of the month, so a period that lands on a non-existent date (like 31 February) moves to the last valid day.
If you add a “check against” date, it also shows the whole number of days remaining and whether that date is already past the deadline. Because every period, start date, and exception is jurisdiction specific, use the result only as a rough planning figure.
Frequently Asked Questions
What is a statute of limitations?
A statute of limitations is a deadline for starting a legal case. Once the period runs out, the court can usually refuse to hear the claim. The length depends on the type of claim and the jurisdiction — this tool does not assume any particular period, so you enter the one that applies to your situation.
When does the clock start?
Often it starts on the date the harm happened. Some claims instead use a 'discovery rule', where the clock starts when the harm was, or reasonably should have been, discovered. If you enter a discovery date, this tool uses it as the start; otherwise it uses the incident date.
Can a deadline be paused or extended?
Sometimes. Rules such as tolling for minors, fraud, or a defendant leaving the jurisdiction can pause or extend a limitation period, and different claims can have different clocks. This calculator does simple calendar math on the period you enter and cannot account for those exceptions — confirm the specifics with a licensed attorney.
Is this the actual legal deadline for my case?
No. It is an estimate based only on the numbers you supply. Limitation periods, start dates, and exceptions vary widely and change over time, so treat the result as a planning aid and verify any real deadline with a qualified lawyer well in advance.
