calculating dates in excel
Calculating the number of days using Excel is pretty simple. Just use a formula to subtract the later date from the earlier date. For example, if cell A1 contains 1-Jan-2004 and cell A2 contains 03-Mar-2004, you simply enter the formula =A2-A1 in cell A3 to get the number of days.At first the result may look strange.owever, calculating the number of months or years between two dates isn't so obvious. There's a Function in Excel that makes this task easy but for some reason Microsoft has hidden it away. You won't find it in the Paste Functions list (Insert, Functions).
