Fasting on Shabbos


Shalom aleichem Rabbi Lauffer, thank you for answering my last question. If one fasts all day on Shabbos but eats after sundown on Saturday, would he have to fast another day for having fasted on Shabbos, or would the fact that he ate, albeit after sundown, cause it to be regarded as if he didn’t fast on Shabbos, and he would thus not have to fast another day. Thanks.



  1. So long as he ate a kezayis within the first thirteen minutes after Shikyah, it is considered as if he did not Fast on Shabbos, and he does not have to Fast again during the week.
