Anash and Bochurim packed the main shul of 770 on Sunday, the second day of Chol Hamoed, to learn the complex laws of Kiddush Hachodesh of the Rambam, which are being learned over the coming days.

The presentation was given by 770 gabbai and renowned Kiddush Hachodesh teacher Rabbi Yosef Losh, who demonstrated these difficult concepts using a globe and props.

Rabbi Losh has been presenting on the topic every year for decades. A video of an early presentation from Tishrei 5748 was published on Anash.org.
