Why are schools closed on Rosh Hashanah?

Schools are closed on Rosh Hashanah because it's a major Jewish holiday. Rosh Hashanah is the Jewish New Year, a time of religious observance and reflection for Jewish people. Closing schools on this day acknowledges the religious significance of the holiday for Jewish students and families, allowing them to participate in religious services and celebrations. It's similar to how schools close for other major religious holidays like Christmas or Easter.
