Christmas

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.

Background

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 OS calendar was January 5, 1783. This would have been the Russian Christmas that year. The next time it happens is January 11, 2543.

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.
