## Gregorian-Julian Differences By Century

On this chart, we'll look at the date differences between the Gregorian calendar, the Julian-1 calendar, and the Julian-Roman-Actual-1 and Julian-Roman-Transitional-1 (versions Julian-Actual-1 and Julian-Transitional-1 for days counting up) calendars.

As we go back in time, we note the differences between the three calendars.

When we get down to 8 C.E. and earlier, we'll use Scalinger's theory on where the leap years on the Julian-Actual-1 calendar may and may not have happened.

According to scholar Scalinger, the leap years were all in B.C.E.: 42, 39, 36, 33, 30, 27, 24, 21, 18, 15, 12 and 9. The first Julian Day, January 1, 45 B.C.E. Julian-Roman-Actual-1, mapped to January 2, 45 B.C.E. on the proleptic Julian-Roman-1 calendar. The first aligned day was on Feb 25 4 C.E. on the proleptic Julian-Roman-1 calendar. The Quadriennial leap year resumed on 8 C.E.

When Pope Gregory XIII introduced his Gregorian calendar to correct the timing of the days of months by using the century where the first Easter day was observed, and lining up the dates of the century between the Gregorian (proleptically) and the Julian-1 calendars. What I discovered is that when I get down to the 5-2 B.C.E. range, and I'm guessing that Pope Gregory XIII never reckoned when thinking of his Gregorian calendar, is that the March 25 date of the conception of Jesus Christ lines up between those same four dates between the Gregorian calendar and the Julian-Transitional-1 calendar. So for those who celebrate the Feast of the Annunciation, also known as the Immaculate Conception of Mary on March 25, if March 25 on the Julian-Transitional-1 calendar is the correct date of this (it maps to March 27 on the Julian-1 calendar between years 5 and 2 B.C. or B.C.E.), it maps exactly to March 25 between those same four years! On the proleptic Julian-1 calendar, it's actually on March 27, but on the calendar the Romans used to correct the timing of the leap year error, it's March 25, the same as that on the proleptic Gregorian calendar! Could this be a Jesus miracle that Pope Gregory XIII never knew about? Also, it's the day celebrating God's preservation of the Blessed Virgin Mary from original sin.

See this excerpt:

Mar 25, 03 B.C.E. Mar 27, 03 B.C.E. Mar 25, 03 B.C.E.
Mar 25, 04 B.C.E. Mar 27, 04 B.C.E. Mar 25, 04 B.C.E.
Mar 25, 05 B.C.E. Mar 27, 05 B.C.E. Mar 25, 05 B.C.E.

Also note that around 5 C.E. when the corrections of the leap year timing were completed after skipping the third year where the intercalary day should have been to speed the calendar up three days, the Julian-Roman-Actual-1 was caught up with the intended dates if the Julian-Roman-1 calendar, so the Julian-Roman-Transitional-1 period ended at that point.

So with that, we proceed.
