There is a custom to honor Rosh Chodesh by eating special foods. Watch as OU Kosher rabbinic coordinator, Rabbi Nosenchuk, explains why. Chazal teach us that the money we spend on celebrating Shabbat and Rosh Chodesh does not diminish the funds that Hashem has allotted to us for the year. Therefore, we are encouraged to do what we can to make Rosh Chodesh special.
