This uses an exclusive day difference: the start date itself is not counted.

Context & Reference

Calculators are most useful when their assumptions are clear. Review these details to better understand the logic behind the results.

The calculator finds the absolute calendar-day difference between the two dates, then breaks it into weeks and days.

Enter both dates and compare the exclusive difference, direction, weeks, days, and approximate hours.

The start date is not counted. Reversed dates remain valid and are identified as an absolute difference.

January 1 to January 10 is 9 exclusive days, which is 1 week and 2 days.

The start date is not counted. Reversed dates remain valid and are shown as an absolute difference with the direction made explicit.
