How weeks between dates are calculated

The calculator first finds the exact calendar-day difference, then divides that span by seven. Full weeks are the whole-number portion and any leftover calendar days are shown separately.

ExampleA span of 24 days equals 3 full weeks and 3 remaining days, or about 3.43 weeks.

Elapsed weeks vs inclusive weeks

Elapsed counting measures the distance from the first date to the second. Inclusive counting adds one calendar day so both the starting and ending dates are part of the span.
