Count number of specific dates within several years

Hello

Hope you guys can help me settle this problem.

A = start date

B = end date

C = count the number of days that fall within 2010

D = count the number of days that fall within 2011

E = count the number of days that fall within 2012

Please see attached data for further info.

Also, I don't know if Excel will account for the fact that 2012 is a leap year.

Thanks
