How to calculate the number of weeks between two dates

To calculate the number of weeks between two dates, start by counting the number of days between the start and end date. Then, divide that number by 7 days per week.
(Start date - End date) / 7 days per week = Weeks between two dates (with decimal)

Example
(3/15/2021 - 3/2/2021) = 13 days
13 days / 7 days per week = 1.857 weeks
Then, convert the decimal point into a number of days. It’s much easier to understand 1 week 6 days than it is 1.857 weeks:
RoundDown(Start date - End Date) / 7 days per week = # of weeks
Remainder(Start date - End Date, 7) = # of days

Example
RoundDown((3/15/2021 - 3/2/2021) / 7, 0) = 1 week
Remainder(3/15/2021 - 3/2/2021, 7) = 6 days
