Jehovah’s Witnesses throw surprise parties for birthdays and gift their families and friends with presents like any other group of people on Earth. However, they are more willing to do it before the actual birthdate of a person. In other words, they don’t tend to celebrate birthdays exactly in the way the other religious groups do. Why is that?
There are only two accounts of birthday parties in the Bible. One of them tells the story of two innocent men, who were imprisoned and then set free, but one of them was later hanged. The other account tells the story of King Herods, who ordered a man to be beheaded on the king’s birthday on his daughter’s request. To sum it up, the both cases show wrongful deaths and injustice.
Whether Jehovah’s Witnesses believe that birthdays are associated with injustice and death, it’s not clear, but it’s a fact that they don’t usually celebrate their birthdays even in present days. However, it wouldn’t be disrespectful of their religion if you present them with a surprise party or a gift.
