Calculate Weeks Between Dates in Excel

Using DATEDIF Function

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.

Calculating Work Weeks with NETWORKDAYS.INTL

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.

Calculating Weeks From Today's Date

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.
