DATE

Builds a date from separate year, month and day values.

Syntax

DATE(year, month, day)

Date & Time.

A worked example

=DATE(2026,8,15)

Returns Aug 15, 2026

Builds a date from year, month and day values.

Where it goes wrong

It normalises overflow rather than erroring: DATE(2026,13,1) is January 2027, which is useful deliberately and confusing accidentally.
