Weeks between two dates
Count how many weeks fall between two dates, with the remaining days included. Handy for a pregnancy, a project, saving up or simply counting down.
To find the weeks between two dates, count the days between them and divide by seven. The whole part is the number of full weeks and the remainder is the leftover days. For example, 30 days is 4 weeks and 2 days. Enter any two dates above for the exact result.
How does it work?
Pick a start and end date. The counter turns the difference into whole weeks plus the leftover days, and also shows the total number of days. Every calendar day counts, weekends included.
How to use it
- Pick the start date.
- Pick the end date.
