The DATE function in Excel is an essential tool for anyone working with dates in spreadsheets. It allows users to create a date using individual year, month, and day components, returning the corresponding serial number of that date. Understanding how to use this function can significantly enhance data management and calculations involving dates.

Syntax

DATE(year, month, day)

• year: An integer representing the year of the date, which can be in two or four digits.
• month: An integer between 1 and 12 specifying the month (1 for January, 2 for February, etc.).
• day: An integer between 1 and the maximum number of days in the specified month, representing the day of the month.

Example #1

Example #2

DATE(2020, 2, 29)

This function returns the serial number for 29th February 2020, which is a leap year, resulting in 44020.

Example #3

DATE(2021, 12, 31)

This call outputs the serial number for 31st December 2021, which is 44561.

Error handling
