Let's Make a Date!

Updated: Apr 20, 2023

Meet Microsoft Excel's 30+Date and Time functions.

Excel calendar

DATE(year, month, day)

Date based on the provided year, month, and day.

Example: =DATE(2023, 1, 15) returns 15/01/2023

Date specified by a particular year, month, and day.

Example: =DATE(2023, 01, 15) returns 15/01/2023


Tip: Use four digits for the year argument to prevent unwanted results. For example, "07" could mean "1907" or "2007." Four digit years prevent confusion.
