There are three calendars we should know when we are talking about Christmas:
- Gregorian Calendar (New Calendar, from February 24th, 1582 to present)
- Julian Calendar (Old Calendar, from 46 BC to present)
- Hebrew Calendar (Old Calendar, from c. 1200 BC to present)
We use Gregorian Calendar in our daily life. This makes us calculating Christmas date using Gregorian Calendar, which did not exist in the time of Jesus. Consequently, many of Gregorian calendar users fail to find biblical verses refering December 25 as Jesus date of birth.
If you fail to find biblical verse on Christmas December 25, it is partly due to use of Gregorian Calendar. Julian and Hebrew Calendars, instead of Gregorian Calendar, were used in Betlehem in the time of Jesus. Use both calendars to find Christmas December 25 in Bible. I found it a long time ago; hopefully, you will find it as well.
