Weeks between dates
See how many complete weeks — plus leftover days — sit between any two dates.
How the weeks between dates calculator works
Enter two dates and this calculator converts the gap into full 7-day weeks plus any remaining days — for example, a 10-day gap is 1 week and 3 days. It is handy for tracking pregnancy weeks, project sprints, rental periods, or age in weeks.
A “week” here means any 7 consecutive days, not a Monday-to-Sunday calendar week, so the count works the same wherever your week starts.
full weeks = floor(total days ÷ 7)
Weeks between dates FAQ
Is a week Monday to Sunday here?
No. A week means any 7 consecutive days, so the result is the same regardless of which weekday your range starts on.
What happens to the leftover days?
They are shown separately. A 10-day gap, for example, is reported as 1 full week and 3 extra days.
Does the order of the dates matter?
No — the tool counts the absolute gap between the two dates either way round.
