- Q. What is the correct order for these fasting days, and why?
A. Mishna Berura (492:3), rules the fasts should always be on the first Monday, Thursday, and following Monday, following the first Shabbat after Rosh Chodesh Cheshvan and Iyar.
However, some communities have the custom to delay the fasts in Cheshvan until the end of the month. Since Shavuos is only one day (or two days in the Diaspora), there is less of a concern that one sinned, and there was no widespread custom to fast after Shavuot.
Nevertheless, there have been individuals who fasted on a Monday, Thursday and Monday after Shavuot.
