MONTHS
Returns the number of months between two dates.
This function is only available if the Analysis AddIn is installed.
Syntax:
MONTHS(startdate; enddate; mode)
- if mode is 0, MONTHS returns the number of whole months between startdate and enddate, day of the month to day of the month (see examples).
- if mode is 1, MONTHS identifies the month that startdate and enddate each lie in, and returns the difference between those months. In other words it returns MONTH(enddate) - MONTH(startdate) + 12 * (YEAR(enddate) - YEAR(startdate)).
- If startdate is after enddate the result will be negative.
Example:
MONTHS("2010-04-03"; "2011-06-17"; 0)
- returns 14, the number of months between 3 April 2010 and 17 June 2011.
MONTHS("2010-03-31"; "2010-04-30"; 0)
- returns 0. 31 March to 30 April is not considered a whole month, even though they are both the last day of their months.
MONTHS("2010-03-31"; "2010-06-30"; 0)
- returns 2. Even though both dates are the last day of their months, the last month is not counted, because the day is less than 31.
MONTHS("2010-04-03"; "2011-06-17"; 1)
- returns 14, the number of months between April 2010 and June 2011.
MONTHS("2010-03-31"; "2010-04-01"; 1)
- returns 1. Even though the dates are just one day apart, they lie in different months.
Issues:
- This function is not available in Excel.
