The Hebrew that is translated as “day for you to blow the trumpets” or “Festival of Trumpets” (New Living Translation) is translated in Tatar as “the day of the sounding of trumpets.” (Source: Lénart de Regt in The Bible Translator 2017, p. 131ff. )
The German Jewish translation by Buber and Rosenzweig has “day of blasts” (Geschmetters Tag).
