I have a content-type which includes boolean fields for winter, spring, summer, fall, (could be more than one season "true" on a given node).

I would like to be able to filter based on season, such that my definition of months-in-a-season, matches today's month.

Seems this need would be common, but I haven't found anything to help me set it up.

Still fairly a newbie here. Appreciate any suggestions.
