And what about:

   Spring Quarter 1999

? Your application will need some rules on what to do with a whole variety
of dates.

What I find in the MARC Holdings documentation is this:
Months and seasons may be expressed either in natural language or by the
following codes: Month:
01-12 - Month

21 - Spring
22 - Summer
23 - Autumn
24 - Winter
I don't know how November/December is coded, nor if there is some kind of
convention outside of the library world for these dates.
