How it works
- Select a start date and an end date.
- The difference in milliseconds is converted to whole days.
- You also see the number of full weeks and the leftover days.
Examples
- From 2026-01-01 to 2026-12-31 is 364 days (or 365 in a leap year).
- Count days until a project deadline or holiday.
- Measure the gap between two events.
