There is an ancient talmudic tradition that affirms that the world was created on Rosh Hodesh Tishrei, a day also known as Rosh HaShanah, the Jewish New Year. Our Mahzor also reminds us that the world was created on this day. So it’s particularly appropriate for Jews to stop and think about how we are celebrating this most ancient Earth Day, how we are honoring the birthday of our home, the planet earth.
