Pick a start and end date to see the total number of days, plus a breakdown in weeks, months, and years.
How does this calculator count months?
It uses calendar-aware month counting, so a span from Jan 31 to Feb 28 counts as a partial month, not a full one. Variable month lengths are handled correctly.
What if my end date is before my start date?
The calculator still works and shows the absolute duration. A small note flags that the end date is earlier than the start date.
Does this count leap years?
Yes — using real Date arithmetic means leap days are automatically included in the total day count.
