It took years for the Board of Education to understand that Jewish High Holiday dates change every year. They are never the same for Rosh Hashana and Yom Kippur. The calendar that determines on which day the holiday occurs is a lunar calendar and the two major holidays rarely if ever will fall on the same day every year.
While teachers were instructed not to begin a new study on the Jewish holidays, rarely is that rule followed. The Jewish population has increased significantly, increasing the number of students affected. I graduated from FHS in 1946. Can’t tell you how many days I was in synagogue and missed school.
