getting data from monthly quarter

Hi there folks, could use a helping hand here if possible. As of right now i have a column that has dates (mm/dd/yyyy) from lowest to largest. I already set up a formula to tell me how many times a job occurs within a year (2001, 2002, 2003 etc).

=SUMPRODUCT(--(YEAR(G2:G174)=2001))

What i need now is instead of giving me all the jobs within one year, i need a formula to give me the jobs within a quater system. So for 2001 how many jobs were between months 01-03, 04-06, 07-09, 10-12. I know i will need at least four rows per year, i really appreciate the help.
