How this calculator works
The calculator uses your browser's current local date and subtracts the number of calendar days entered.
The tool is arithmetic only. Where legal, payroll, holiday, timezone or jurisdiction-specific rules matter, the page states what is and is not included.
Frequently asked questions
Does it account for leap years?
Yes. Calendar arithmetic uses real date boundaries, including February 29 where applicable.
