Converting Date Of Birth To 'Term Of Birth'

Is it possible to convert a students DoB into their term of birth (ToB).

I.e. a student has the DoB of 1/1/2001 which would mean their ToB would be 'Spring'

I suppose what I'm after is...
If a DoB falls into one of three groups
1/1/year to 30/4/year = 'Spring'
1/5/year to 31/8/year = 'Summer'
1/9/year to 31/12/year = 'Autumn'

The year of birth is irrelevant, it's the month which determines the 'term of birth' (Spring/Summer/Autumn).
