During Yom Kippur, adult Jews fast for 25 hours, this fast means no food or water. We refrain from all work and spend the day in synagogue atoning for our mistakes of the previous year and asking HaShem to seal us in the book of good for the upcoming year. Once Yom Kippur ends, we break our fast with family and friends.
