The circumcision of Jesus is an event from the life of Jesus, according to the Gospel of Luke chapter 2, which states:

And when eight days were fulfilled to circumcise the child, his name was called Jesus, the name called by the angel before he was conceived in the womb.

The eight days after his birth is traditionally observed 1 January. This is in keeping with the Jewish law which holds that males should be circumcised eight days after birth during a Brit milah ceremony, at which they are also given their name.
