Subtracting quarters?

Hello! Thank you in advance for the help.

I need to subtract quarters. For example, Q413-Q113=3. I cannot figure out how to do this.

An alternate solution would be to convert the quarter to a date and subtract the dates, but I cannot figure out how to convert Q113 to 1/1/13, The dates go back too far to use nested if.

I appreciate any help.

What is your expected result? Are you trying to calculate the length in days of each quarter?

Without knowing the values of Q413 or Q113 it's difficult to discern your intentions.

I am trying to determine the number of quarters.

XOR LX, That worked like a charm! Thank you so much!
