Returns the year corresponding to serial_number. The year is given as an integer in the range 1900-9999.
Serial_number is the date-time code used by Microsoft Excel for date and time calculations. You can give serial_number as text, such as "15-Apr-1993" or "4-15-93", instead of as a number. The text is automatically converted to a serial number. For more information about serial_number, see NOW.
Microsoft Excel for Windows and Microsoft Excel for the Macintosh use different date systems as their default. For more information, see NOW.

If you are using the 1904 date system (the default in Microsoft Excel for the Macintosh), then:
YEAR(0.007) equals 1904
