Until When May One Read Shnayim Mikra Ve-Echad Targum?

Greetings, It is preferable, ideally, to complete the reading of Shnayim Mikra Ve-Echad Targum before eating on Shabbat. If one did not manage to complete it before eating, one should complete it afterward, until the Mincha prayer. Bediavad, it may be completed until Tuesday night. If one did not do so, one should endeavor to complete it as soon as possible, until Simchat Torah. Sources: See Shulchan Aruch (siman 285, seif 4). 

Shabbat Shalom, 

Hillel Meirs
