Excel - extract month from date

Lets say that cell A1 contains the date July 21, 2004 (entered as 21/7/2004 or 7/21/2004 depending on your date system). You want to extract the year (i.e. 2004) from that date and put it in cell C1. Simply enter the formula =YEAR(A1) in cell C1. Same thing for month and day. Use =MONTH(A1) or =DAY(A1).Then reformat as text
