Shavuot, the “Feast of Weeks,” is celebrated seven weeks after Passover (Pesach). Its origins are to be found in an ancient grain harvest festival.
A famous symbol of Shavuot are The Seven Species (Hebrew: שבעת המינים, Shiv'at HaMinim). These are seven agricultural products - two grains and five fruits - which are special products of the Land of Israel. The seven species are wheat, barley, grape, fig, pomegranates, olive (oil), and date (honey). The seven species are traditionally eaten on Tu Bishvat, the Jewish "New Year for Trees", on Sukkot, the "Festival of Booths", and on Shavuot as well.
One of the holiday's traditions is eating of dairy products. Although the reasons for this custom are not completely clear, it has become traditional to eat milk and cheese products as part of the celebration of Shavuot. Maybe it is because of the ancient saying about Israel - "a land of milk and honey". Israeli families usually have a Shavuot dinner or lunch together, eating Pies, salads, fruits and off course - no Shavuot meal is complete without a slice of cheesecake!
Kids usually dress in white for school and bring with them baskets filled with crops like fruit and vegetables to celebrate the harvest festival. They usually have a show of dancing and singing, presenting the crops.
Happy Shavuot!
