calculating per quarter

[bklex]

I want my spreadsheet to calculate days per quarter, as in every quarter
employees are given 'x' days of vacation time. How do I do this?

Hi

If you put the number of the quarter in cell A1 (so 1, 2, 3 or 4), and the
year in A2, then put in:

B1: =DATE(A2,(A1-1)*3+1,1) to get the begin date of the quarter
C1: =DATE(A2,A1*3,0) to get the ending date of the quarter
D1: =C1-B1 to get the number of days in between
