Syntax

EOMONTH(when, offset-months)

  • when - A Date or DateTime value.
  • offset-months (Number): A number of months to add to or subtract from when before computing the last day of the month. For instance, 0 would find the end of the month specified by when; 1 would find it for the month after when; and -1 would find it for the month prior to when.

Note

Some constant values, such as "MM/DD/YYYY", are evaluated as a Date value by AppSheet. Similarly, "000:00:00" is evaluated as a Duration value. This doesn't mean your spreadsheet data must use the same formats: the date and time formats in your spreadsheets are determined by the locale/language setting. Column will always be evaluated as the type of column. Additionally, you can convert data, both columns and string literals, to specific types using functions such as DATE(), TIME(), or DATETIME().
