How this calculator works
The calculator compares the chosen date with today's local calendar date and reports the difference in whole calendar days.
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
What if I enter a future date?
The result indicates that the date is still in the future rather than presenting a misleading elapsed-days count.
