Chadash

In Judaism, Chodosh (or Chadash) (Hebrew: חדש ; "new ") is a concept within Kashrut (the Jewish dietary regulations), based on the Biblical requirement not to eat any grain of the new year (or products made from it) prior to the annual Omer offering on the 16th day of Nisan.

Grain products which are no longer affected by this law are referred to as Yoshon (= old).
