It’s common knowledge that Rosh Hashanah, the first day of the Hebrew month of Tishrei, is the Jewish new year. And yet, despite the obvious importance of this High Holy Day, the Bible quite clearly stipulates another month entirely as marking the true beginning of the Jewish year. That is the month of Nisan, whose first day falls this year on Saturday, April 6. By dint of its connection to the story of the Exodus from Egypt, Nisan would indeed seem to be the most important month of all.
