Questions about time

How is exact age calculated?

The calculator counts completed calendar years and months, then the remaining days.

Why can month lengths affect the result?

Calendar months contain different numbers of days, so exact calendar differences are not the same as dividing elapsed days by 30.

Are my dates saved?

No. Calculations happen locally in your browser.
