How this calculator works
The calculator compares the selected date with your browser's current local date and reports the signed calendar-day difference.
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
