While various parties have called for a ceasefire between Russia and Ukraine, the fighting continues (Al Arabiya, Daily Beast, Parley Policy Initiative). An announced ceasefire must be acknowledged by both Russia and Ukraine to count, and must include the whole of Ukraine. For the purposes of this question, "Ukraine" includes the boundaries generally recognized by the international community, including Donbas and Crimea. The Ukrainian government as recognized by the European Union must be party to the announced ceasefire to count. The date a ceasefire would take effect is immaterial.
