Veelgestelde vragen
- What can it calculate?
- Two things: the number of days (and weeks/months/years) between two dates, or a new date after you add or subtract days, weeks, months, or years from a starting date.
- How does adding months handle month lengths?
- It uses calendar arithmetic, so adding 1 month to 31 January lands on the end of February rather than overflowing into March. Adding days instead avoids that ambiguity.
- Does it handle leap years?
- Yes. Differences and date shifts use real calendar dates, so 29 February and leap days are counted correctly.
- Are my dates uploaded?
- No. The result is computed from the dates you pick using the browser's built-in date functions, so nothing leaves the tab.
