Being a student of cultural study it is my core interest to learn about different cultures and their norms around the globe. Israel has been a high place in different religions of the world. Being a sociologist it is very important to know the societal influences of the customs and as you mention it sounds that people are always very happy with such events.
We are now it the "Feast of unleavened bread" as it's called. This is a Mitzvah given by God to Mosheh (Moses). Fun fact: When a male child comes of age they throw a party called a "Bar Miszvah" meaning son of the commandment or instruction.
Since i followed you, i have learnt a few basics of this wonderful Hebrew language. I am obliged to you for giving me so much.
Peace to you @hebrew :) :)
