Subtract Days from a Date in Excel

To subtract days from a date in Excel, simply use a basic subtraction formula. Excel stores dates as serial numbers, which makes it possible to perform subtraction on dates as if they were numbers. For example, if you want to subtract 10 days from a date in cell A1, you would use the formula =A1-10.

Using Excel Functions

Another method to subtract days is by using the DATE function. This function allows for the subtraction of days, months, and years from a date. To subtract days using the DATE function, you would input the year, month, and the day as separate arguments. For example, =DATE(YEAR(A1), MONTH(A1), DAY(A1)-10) subtracts 10 days from the date in cell A1.

Subtraction Across Different Years

If you need to subtract days from a date that may result in the year changing, Excel can handle this as well. The DATE function can be used to accurately subtract the days and account for the year change without any additional adjustments needed.
