In column "G" I have imported dates formatted as such...11/09/2009 9:58:00 AM

I'm in accounting so we go by fiscal month i.e. 10/24/09 thru 11/27/09 is
November

I'm looking for a formula that will tell me what month the date falls in.

I tried this...(not working)
=IF(OR(G7="09/26/2009","October",IF(G7<="10/23/09","October",IF(G7="10/24/2009","November",IF(G7<="11/27/09","November",IF(G7="11/28/09","December",IF(G7="12/31/2009","December",FALSE)))))))

I'm not sure if I'm even on the right track.

Please help

Thank you,
T
