What is the last day of the month that falls 6 months after September 14 2001?
- =EOMONTH(DATE(2001;9;14);6)
returns the serial number 37346. Formatted as a date, this is 2002-03-31.
-- =EOMONTH("2001-09-14";6)
works as well. If the date is given as string, it has to be in ISO format.
+- =EOMONTH("2001-09-14";6)
works as well. If you specify the date directly, we recommend using the standard ISO 8601 format because this should be independent of your selected locale settings.
