The shtei halechem are eaten no earlier than two [days] and no later than three [days]. How so? [If] they are baked on the eve of the Festival and eaten on the Festival, that is two. [If] the Festival falls on Sunday, they are eaten on the third. The lechem hapanim are eaten no earlier than nine [days] and no later than eleven [days]. How so? [If] they are baked on Friday and eaten on the Sabbath, that is nine [days]. [If] a Festival falls on Friday, it is eaten on the tenth [day]. [If] the two days of Rosh Hashanah, it is eaten on the eleventh [day]. It does not override either the Sabbath or the Festival. Rabban Shimon ben Gamliel says in the name of R’ Shimon the son of the administrator: It overrides the Festival but it does not override the day of the fast.
