Men and boys from 13 yrs old have to pray with a minimum of 10 men called a minyan. They have to do whatever they can not to miss praying with a minyan. There are 3 prayers a day: morning, afternoon and night.
When we go on vacation, we can only go to places that have a minimum of 10 men so that a minyan can be formed. That’s why you usually find groups of Jews vacationing together. 😀
