Use the Function NOW() - put it in cell A1, - this gives you the curren
date.
Put your date in cell A2
In cell B2 enter the following formula =(A1-A2)/365
I used the following format for cells A1 and A2 Date Format - 14 ma
98
Then use a "General" Format for Cell B2
This will give you a number with a decimal point - the numbers to th
left of the decimal point = years, to the right will be the months.
