Sum Days in Excel

Using Simple Formulas

Excel calculates the sum of days by treating dates as serial numbers. Add or subtract days by using basic arithmetic in formulas.

Using EDATE Function

The EDATE function modifies a date by a specific number of months. The syntax is EDATE(start_date, months), where 'start_date' is the initial date and 'months' is the number of months to add or subtract.

Using DATE Function

The DATE function changes a date by adding or subtracting years, months, and days. Utilize DATE(year, month, day), injecting adjustments into each argument as needed.

Using DAYS Function

Calculate the total days between dates with the DAYS function. The formula is DAYS(end_date, start_date), which necessitates two numeric date values.
