I have a textbox which takes academic year as input in the form (YYYY-YY, for example 2013-14). How can I create a validator for this format?

I would suggest you use System.DateTime.TryParse or System.DateTime.TryParseExact with appropriate time format string or culture:

However, making a user to input date or time is a text box and then validating it is not a good idea. Why not using DateTimePicker instead? For example, please see:
DateTimePicker Web Control[^].
