I am using the following formula in a calculated column for a list:

=MONTH([Some Date])

If the value of Some Date = '2/4/2005', the formula returns '2'. When I
go to do a "Group By," it groups my data by 1, 2, 3,...etc. How do I
set the month number to the corresponding month 'January,
February,..etc? Is there a way to do this inside my formula using an
if then or case statement? It seems doable.
