Special Events in CPH! (Copenhagen)

Dear CPH friends,

I'm in CPH since October and will stay until early April. A very good italian friend of mine is a writer and would like to have an "excuse" to come and visit me! He would like to tell and write something about any special event taking place in CPH or in Denmark in the next couple of months! It could be anything: Carnival, popular celebrations (spring?), funny traditions, bike trips. I'm trying to investigate myself but I need also your help!

Thanks in advance
Elisabetta
