In Japan's case, that was the 9th of March actually.
Same with eastern Europe, Russia, and all of Asia and Oceania.
Central Europe was still on the 8th, but by the time it ended it was almost the 9th.
Details that still include a majority of the world population actually, especially considering Asia alone already covers 54% of the entire world, then all of Oceania gets included, a bit of Europe, and a big deal of Africa.
