Basic Date Subtraction in Excel
Subtracting dates in Excel is straightforward. For example, if you have a start date in cell A1 (15/01/2020) and an end date in cell B1 (20/01/2020), use the formula “=B1-A1” to find the number of days between them.

Using the DATEDIF Function for Detailed Calculations
For more specific calculations like months or years between dates, use the DATEDIF function. The formula is “DATEDIF(start_date, end_date, unit)”, where “unit” is “D” for days, “M” for months, or “Y” for years. For example, “=DATEDIF(A1, B1, “M”)” calculates the complete months between two dates. This function offers precise time calculations for various needs.
