Date Time format issue

Hi All

We use a field in Sugar to record our Race Dates and the format is date - time (See below). My question is how can I get a report that shows all the January or Feb event etc. I seem to be stuck due to the date-time format. Is there away of adding up all the dates for a month and reporting them as one amount?
