Finding upcoming rallies in Europe

Where can I go to lookup any Palestine demonstrations due to take place throughout the EU, ideally with more advance notice than like... a few hours or a day? Around a week at least would be best so I can buy tickets and not when work is in the way. Looking specifically for something taking place on 18-19 and 25-26 November.

isn't an option, however.

Getting arrested isn't going to deter me.
