Enter your values. Your result will appear here.
How it works
- Enter a start and end date.
- Choose elapsed or inclusive day counting.
Example & practical use
2025-01-01 to 2025-01-02 → 1 elapsed day
What to know
End must be on or after start. Dates use UTC calendar boundaries, so daylight-saving changes do not affect the count. Calendar decomposition always uses the elapsed interval and clamps month ends.
