After Shavuot

The day after Chag is known as “Yom Tovo’ach”. It is also Isru Chag, and should be celebrated with additional food items. One may not fast on this day – even a Chattan and Kallah on their wedding day.

The days after Shavuot until the twelfth of Sivan (inclusive) are known as “Y’mei Tashlumin”, during which Tachnun is not recited, however, some people have the custom to say Tachanun. The Baal Hatanya once remarked that these are the days to “pack” all the treasures and revelations of Shavuot.
