Hi,
Here is one solution
=YEARFRAC(--"1/1/09",--"1/1/09"+750,1)
An alternative is to use the DATEDIF function, and since you didn't give us
a starting date:
=DATEDIF(--"1/1/09",--"1/1/09"+750,"Y") whole years
=DATEDIF(--"1/1/09",--"1/1/09"+750,"YM") whole months left over
=DATEDIF(--"1/1/09",--"1/1/09"+750,"MD") days left over
