Hi. Just a simple question that I tried to ask my rabbi today but I never understood his answer and I was to embarrassed to show my ignorance by asking him to explain his answer.
I don’t attend Shul services often. Only for mincha and Neilah on Yom Kippur and today when I had to say Kaddish.
I do however remember that on Yom Kippur we said a prayer at the end and banged our chests.
Today the rabbi announced that seeing as it’s Nissan there’s no banging of the chest. After the service I asked him why. He told me it’s because there’s no tachanun in Nissan.
But I don’t understand, what is tachanun, what’s the connection to banging the chest, why is there no tachanun in Nissan and is there tachanun on Yom Kippur?
