To calculate the number of weeks between two dates in Excel, you can use the DATEDIF function. This function is versatile, allowing you to compute differences in days, weeks, months, and years. For weeks, divide the number of days by 7. The formula is as follows: =DATEDIF(start_date, end_date, "d")/7
. Replace start_date
and end_date
with your specific dates.
If you need to calculate the number of workweeks, excluding weekends and holidays, use the NETWORKDAYS.INTL function. This function returns the number of workdays between two dates. To convert workdays to workweeks, divide the result by 5: =NETWORKDAYS.INTL(start_date, end_date)/5
. Adjust the formula to exclude specific weekends or holidays as needed.
To find out the number of weeks from today’s date to another date, combine the DATEDIF function with the TODAY() function: =DATEDIF(TODAY(), future_date, "d")/7
. This will give you the time span in weeks from the current date to the specified future_date

Use the DATEDIF function with the 'd' argument to calculate days between dates, then divide by 7. For example, if your start date is in cell A1 and end date in B1, the formula would be: =DATEDIF(A1,B1,'d')/7
After calculating the weeks, press CTRL + 1 and select Number > Decimal places: 2 to format the result with two decimal places
The basic formula structure is DATEDIF(start_date, end_date, 'd')/7, where 'd' returns the number of days which is then divided by 7 to get the number of weeks
