You could take a look at some of the Regular Expression tools here on this site:
Expresso - A Tool for Building and Testing Regular Expressions[^]
Regular Expression Library Builder[^]
Regular Expression Tester[^]

This sould be engough for your purposes, however Id use normal String maipulation or a combobox if I were you.

Solution 2

You mean ASP.NET.
Why don't you give the user a dropdown instead of a textbox, anyway?

Still, you can user regular expression validator[^]. The expression in your case is a simple enumeration: ^(january|february|march|and so on)$
Of use custom validator[^] and validate from code against an array

+5. Yes, a dropdown box would make more sense. Possibly even a date picker (which I believe will automatically adjust to the user's language). But the links provided, and the example expression, if they must stick to the regular expression method, also look helpful.
