Carneval is also somewhere in February/March. This is because in germany we have two types of carneval; "Karneval" which traditionally opens on 11.11 and "Fasching" which usually happens around ash wednesday in spring, both translate to "carneval" in english, both do the same thing, though supposedly they're the two ends of the winter season. Fasching usually also happens more in the southern regions of germany, to my experience.
