I will resolve based on the (de facto) end date on this Wikipedia page: https://en.m.wikipedia.org/wiki/Russian_invasion_of_Ukraine I will wait until the end date has been the same for a full 24 hour period. I will resolve in line with the Wikipedia editors unless it's clear that this is not in line with the "spirit" of the question. The spirit of the question is about when the armed conflict substantially stops regardless of who controls what territory. A temporary ceasefire does not count. [image]I may change the criteria to clarify questions or fix flaws. I will not bet in this market.
