=DATE (YEAR (TODAY()), MONTH (TODAY ()), 1): This function returns the first day of the current year and month.

=DATE (2018,3,20) – 5: This subtracts 5 days from March 20, 2018.

Examples

=DATEVALUE("20-March-2018"): Returns March 20, 2018

=DATEVALUE("March 25, 2018"): Returns March 25, 2018

Syntax

=DATEDIF (old date, new date, "d")

## 7. Subtract date from the current date

To subtract dates using the current date, use TODAY ().

Syntax

=TODAY ()-OLD DATE

Or

=DATEDIF (OLD DATE, TODAY(), "d")
