How this works
The "Difference" tab counts the exact number of calendar days between two dates. The "Add / subtract" tab moves a date forward or backward by a number of days, correctly rolling over month and year boundaries.
Examples
- Countdown: from 6 September 2026 to 25 December 2026 is 110 days.
- Deadline: 45 days from 1 January 2026 lands on 15 February 2026.
