Jews all over the world celebrate the new year. Rosh Hashanah is celebrated for two days in a row. The holiday is considered the birthday of humanity and the creation of the world. Among the obligatory traditions are the analysis of one's actions for the previous year, their rethinking and repentance. And preparation for the coming year. And a separate branch - the Hasidim gather at the grave of Tzadik Nachman in Uman. Because that's what their mentor commanded them.
