This is very helpful. I visited Berlin briefly in July for too short a time and need to go back and explore properly.
I am amazed at the number of events! I hope that you can also enter some events in the distant future so us foreigners can plan trips to attend. For instance, I hope to make it to the Berliner Weisse Gipfel on 18 March, which is not yet on your calendar. Also, if you enter some of the larger events on the RateBeer calendar, you’ll get a wider audience, then just add a link to your site.
Best of luck!
