Was Jesus really born on 25 December?

Open navigator

1. Born on Christmas Day

Christians celebrate the birth of Jesus on 25 December. However, early believers didn't mark the event as they considered it a pagan practice. They also expected their Messiah to return soon and bring about the end of the world as foretold in biblical prophecies.

But by the 3rd Century Christians had begun to organise their ministry and debate the merits of various feast days to mark Jesus’ birth. Suggestions for Christmas included 21 March and 20 May.

Yet by 336AD the Church of Rome, now accepted by the Roman Empire, had settled on 25 December. How they got there reveals much about the young religion.

2. How did they decide?

The Gospels of Matthew and Luke didn’t mention when Jesus' birth was. So why did the Roman Church adopt 25 December?

Pagan festival

Did they adopt Saturnalia, a Roman festival of gift-giving and feasting that was celebrated in December?

This is


Saturnalia was celebrated earlier in December and Christian writers don't mention adapting their calendar to fit in with it. Pagan revelry was adopted later.

Celebrating sun god

Did they adopt the Roman sun god, Sol Invictus, and simply replace Sol with Jesus as the 'light of the world'?


Probably helped

Debate about 25 December preceded Rome's adoption of Christianity, so it wasn't where the date came from. But it could be why Roman Christians then favoured it.

As good a date as any

Could it have been a random selection from the Roman Julian calendar?

This is


Early Christians were steeped in theology, using reason to increase their grasp of their religion. They would have had a rationale for picking 25 December.

Religious reason

Early Christians mined the scriptures for symbolic meaning as well as facts. Could this have influenced their choice for Christmas?

This is


Christian authors writing in the 3rd Century were exploring theological arguments for when Jesus might have been conceived and therefore born nine months later.
