How do I change the following formula to allow for leap year

[Linda432]

I am using Excel 2000.

I have a spreadsheet that calculates the hours used in the last rolling 12
months for FMLA. The fomula I have works but I need to allow for leap years.
How do I change the formula?

The formula in column C is: =sumif($A$2:A2,">"&A2-365,B$2:B2)

Col A Col B Col C
Date Hours used Hours in past 12 month period
1-1-07 1.00 1.00
2-15-07 5.00 6.00
2-5-08 3.00 8.00

Thanks for your help.
Linda

try
=sumif($A$2:A2,">"&DATE(YEAR(A2)-1,MONTH(A2),DAY(A2)),B$2:B2)

HTH. Best wishes Harald

You could use

=SUMIF($A$2:A2,">"&DATEVALUE(MONTH(A2)&"/"&DAY(A2)&"/"&YEAR(A2)-1),B$2:B2)
