Rabbi Yosef Yitzchok Losh, a native of Kfar Chabad, Israel, studied in yeshivot in Newark, NJ, and Yeshivat Tomchei Temimim ("770") in Brooklyn, NY. Rabbi Losh is one of the gabbaim in 770, the synagogue based at Lubavitch World Headquarters. An amateur astronomer, he lectures widely on astronomy in Jewish law, covering topics such as how new months are calculated and the "Blessing of the Sun," a once-in-twenty-eight-years mitzvah.
Have you ever wondered why you need to wait to bless the moon? How the calendar calculates from one molad to the next? Why the visibility of the moon changes from quarter to quarter? Rabbi Yosef Yitzchok Losh takes us inside this technical matter with the use of diagrams, models, and calculations
