No, Jesus was not born in a leap year. The most commonly accepted range of years for Jesus' birth is between 6 BC and 4 BC. None of those years were leap years.
Here's why:
* The Gregorian calendar (which includes leap years) didn't exist at the time of Jesus' birth. The Julian calendar was in use then, and it had a different system for leap years.
* Leap years were introduced to align the calendar with the solar year. The Julian calendar initially had some inaccuracies in its leap year calculations.
* Based on the range of likely birth years (6 BC to 4 BC), none of those years were Julian leap years.
Therefore, it is highly improbable that Jesus was born in a leap year.
