Tonight is New Year's Eve in the Julian calendar. (Excuse for a party ?)
Posted by Bruce McClure in Tonight | January 13, 2020
Today’s date – January 13, 2020 – may be just another Monday in the Gregorian calendar, but it’s the last day of the year by the Julian calendar, which was first introduced to the world by Julius Caesar in 46 B.C. It’s the Julian New Year, sometimes called the Old New Year or the Orthodox New Year.
Tomorrow – January 14, 2020 – will be January 1 in the Julian calendar.
Historians and other chronologists care about the Julian calendar because it was used worldwide for over 16 centuries. Some – for example, the Christian Eastern Orthodox Church – still use the Julian calendar to this day.
But most of us don’t use it. After the inception of the Gregorian calendar on October 15, 1582, more and more people slowly but surely came to adopt the Gregorian calendar, which is now used nearly everywhere worldwide.
For astronomers and astronomy enthusiasts, it’s good to know that chronologists use the Julian calendar date for dates of celestial events occurring before the Gregorian calendar was introduced. For instance, equinoxes and solstices and any lunar and solar eclipses happening before October 15, 1582, are dated by the Julian calendar.

Slightly disappointed to realize that Frederik Pohl's short story Day Million is not based on the Julian Date.
We're coming up on Day Two and a Half Million.
This is a PSA for those who were disappointed in the Gregorian New Year's, and would like a do-over.
