The birthdates of John the Baptist and Jesus are not generally known, but 5 BC is often assumed to be the date. The spring Passover feast (often around April 21) has been cited as a possible date for the birth of Christ, assuming that this had relevance to being a Messiahclaimant, or that his birthday might have been related to Passover. Others theologically tie his birth to Sukkot, the fall Feast of Tabernacles.
