I believe contemporary theatre covers at least back as far as 1930. I'm not coming at this from any historical angle, just a lot of audition prep. In preparing a contemporary monologue, you are generally advised to keep more up-to-date than the likes of Wilde and Shaw, because you don't know what the audition panel is going to consider contemporary, and it's better safe than sorry.
So definitely the last 50 years, but beyond that, definitions get more nebulous and more likely to vary from person to person.
I would be suprised if you get many brownie points at an interview if you expand on your love for Coward and Rattigan when asked about contemporary theatre...
