Jewish people attend religious services and do not eat from sundown to sundown

The fast  goes for about 25 hours, and during that time followers  are not allowed to eat or drink anything, including water 

after the  Day of Atonement is over, a "shofar" horn is blown to mark the end of the fast and a festive meal is prepared to break the fast

According to lore, the origins of Yom Kippur can be traced to Moses' leading the ancient Israelites out of slavery 

No matter how you spend the day, it's a time to atone in your own way, whether in a synagogue or at home.
