Question
I want to know about Jewish fasting. Which days are fast days and when can one eat?

Question
Shalom aleichem Rabbi Lauffer. Thank you for answering my last question. Would it be permitted to play softball on Shiva Asar b’Tammuz in the rain, or would this be forbidden because one might come to inadvertently swallow raindrops? Also, I heard there was a difference between eating food cooked on Shabbos and food cooked on Yom Kippur - the food cooked on Yom Kippur being more stringent in this case. Would food cooked b’shogeig on Yom Kippur be permitted after the fast, or would it be forbidden forever? Thanks a lot.

Question
Is there any special mitzvah to fulfill on the festival of Shavuot? Like matzah on Passover? Thanks
