Q&A  > dates and times


I'm sure this is a dumb question, but I can't seem to find the answer. I have a variable that contains a month name i.e. "October" I want to change that to the number i.e. "10". Is there an easy way of doing this. My only thought was
if ($var eq "January") { $var=1; } elsif ($var eq "Feburary") ...
but this seems rather long and tedious.

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.

if you prefer monolithic modules, try Date::Calc, or Date::Manip
