The Christmas holiday lands at an essentially random date on the Bible Calendar. There are a few places in history where the date really has been on Jesus’ birthday. This article provides a date report showing the dates in question.
A previous article showed that Ash Wednesday is the cultural memory of the birth of Jesus. The key points there being the timing ahead of Easter, and the ceremony itself referencing Adam's fall. Jesus' birth was a prophetic match to Adam's life.
There are often debates about Christmas, could it be correct? Most likely it is an early Church attempt to repurpose Saturnalia. The Christmas wreath a memory of the rings of Saturn, and so on.
The question that still remains, is how often is Christmas landing on the correct date?
Because prophetic time is measured on a calendar out of phase with modern calendars, Christmas can be on the right date every so often. What follows here is exactly when those dates are correct.
Julian Calendar Christmas
Because the Bible Calendar is out of phase with the Roman/Christian calendar it is possible for certain occurrences of Christmas to land at exactly the correct place to be an actual birthday. The following report explores.
The last time this happened on the Julian calendar was 5 January 1783 OS. This would have been the Russian Christmas that year. The next time it happens is 11 January 2543 OS.
Gregorian Calendar Christmas
The other general type of Christmas dates follows the Gregorian calendar. The following provides the dates when this happened. Christmas in 1784 is the last time that Christmas fell on the Biblical anniversary of Jesus’ birthday in the English world. It does not happen again until 25 December 2591 NS.
These reports are a wonderful demonstration of the quirks of parallel calendars. If you understand these reports and what drives their structure you probably have the calendar issues understood.
