    ^^^^^^^^^^^^^^

Herein lies the problem. The '==' comparator only works for numbers. If you
want to compare strings you need to use strcmp:

if (strcmp(month, "january") == 0) ...

strcmp returns 0 for an exact match; non zero otherwise. Further details in
the online help[+]. You might also like to check out strcasecmp and strncmp
for useful variations on a theme.

Yours,

Neil
