The religion that does not believe in celebrating the birthdays of individuals is called Jehovah's Witness. Jehovah's Witnesses are individuals who do not celebrate birthdays of fellow church members, but instead recognize and honor only the birth of Christ. Witnesses also do not ascribe to other societal customs, such as standing for the national anthem, and refusing certain medical procedures, such as blood transfusions.
Jehovah's Witnesses, like people who ascribe to other religions, are found around the world. They faced prosecution during the 19th and 20th centuries, first by the Church of England, and then by the Nazis in Germany during the 20th century. In Germany, some members of the Church of Jehovah’s Witness were sent to concentration camps, along with Jews and other marginalized religious and social groups. Jehovah's Witnesses also hold a unique view among many religions in that they believe Jesus Christ to be the son of the Angel Gabriel rather than the Son of God. Jehovah’s Witnesses believe in Armageddon, and see their mission on Earth as one of evangelism, which bears them the task of spreading "good news" to individuals in society (primarily other Witnesses) who will be saved on the day that God enforces his dominion on all people and animals on Earth.
