I select these events based on my interests and geographic proximity. If you notice I'm missing something relevant, please tell me! Also note that I probably won't go to most of these.

#### Looking for other conferences and summer schools?

To find out where the interesting stuff happens, I recommend

Andreas Holmstrom's list of lists of events as well as The SPP 1786 priority programme 'Homotopy Theory and Algebraic Geometry' event list and the (relatively young) MathMeetings.net. Also, the announcements from the Graduiertenkolleg "Cohomological Methods in Geometry" in Freiburg can be quite interesting!
