You want a hash.
%mon2num = qw( jan 1 feb 2 mar 3 apr 4 may 5 jun 6 jul 7 aug 8 sep 9 oct 10 nov 11 dec 12 ); print $mon2num{ lc substr($month, 0, 3) };
That works for "JANUARY", "Mar", "decemb.", "oct", and many other variants.

    Great implementation japhy! A word of warning to the wise that if you plan on using this with POSIX mktime and friends you'll want to subtract 1 from the month number (e.g. January = 0, December = 11).
