How the Date Difference Is Calculated
This calculator finds the duration between two dates two ways: a precise years / months / days breakdown, and the simple total number of days (and weeks) between them.
Common Uses
- Counting days until an exam, deadline, wedding or trip.
- Working out exact age or length of service.
- Tracking notice periods, contracts and warranties.
- Finding how long ago an event happened.
Frequently Asked Questions
Does it account for leap years?
Yes. The calculation uses real calendar dates, so leap years and varying month lengths are handled correctly.
Can I find a future date instead?
This tool measures the gap between two known dates. To add days to a date, an age or countdown tool is better suited.
