Calendar 6: The Julian-Roman-Transitional-1 Calendar

The Julian-Roman-Transitional-1 Calendar (Number Change Day on January 1, with no leap year days the Romans used from 8 B.C.E. through 4 C.E.)

1. A modification of the Julian-Roman-Actual-1 calendar by Augustus Caesar to be effective January 1, 746 UAC, translated to Julian-Roman-Transitional-1 year 8 B.C.
2. The Julian-Roman-Transitional-1 calendar (aka Julian-Roman-Kalends-Transitional-1) was introduced in 746 UAC (or 8 B.C.) with no years with leap year days through 4 C.E.
3. There were no leap years from 8 B.C. until 8 A.D., skipping the years 5 B.C., 1 B.C and 4 C.E. that would have been leap years.
4. After 4 C.E., the Julian-Roman-1 calendar (fully implemented edition) was in effect with the current one leap year day every four years rule in 758 UAC (or 5 A.D.) after going several years without a year with a leap year day.
5. This was meant to be a short era of calendar usage to gradually align the timing of the dates misaligned with the Julian-Roman-Actual-1 calendar to that of the Julian-Roman-1 calendar (which would be the base dating format for the Julian-1 calendar later on), which would then be the basis of the Julian-1 calendar with a different year of reckoning.
6. The purpose of this special era was to realign the Julian-Roman-Actual-1 calendar with the intended date it should have been to match the intended solar day of the tropical year.
7. This is a Transitional calendar, meaning, it's a substitute calendar to correct the incorrect timing of the too-frequently placed leap year days by having no leap year days to speed up the calendar. It's an overlay of the rule of no use of a leap year during the first 12 years (years 5, 6 and 7 A.D. weren't leap years naturally) of the revised Julian-Roman-1 calendar.
8. This short transistional calendar system is not to be used as a Proleptic calendar of any year of reckoning.
9. The Julian-Roman-Transitional-1 Calendar is identical of the Julian-Roman-1 and Julian-Roman-Actual-1 Calendars with the following differences:
1. There may or may not have been a leap year day on 4 A.D. Most scholars, but not all, agree that it wasn't a leap year.
2. The proleptic Julian-1 calendar (before 8 B.C. and of the Christian era) has a leap year every four years while the early years of the Julian-Roman-Actual-1 calendar had leap years placed too frequent or in unpredictable years.
3. Because the Julian-Roman-Actual-1 calendar technically had a leap year every three instead of four years, the Julian-Roman-Actual-1 calendar was three days slow.
4. To help the calendar catch up to the intended timing of the leap years on the Julian-Roman-1 calendar, there may have been three years, 5 B.C., 1 B.C. and 4 A.D. that were declared leap-year-less years, skipping three leap years until the calendar was calibrated with the intended date of the Julian-Roman-1 calendar for the solar day of the year.
5. Since nobody knows for sure which years between 45 B.C. and 4 A.D. were or were not leap years, the dates during this time range may not be an exact match for the corresponding Julian Period Days.
6. in order for the dates between Julius's design to line up with the Julian-Roman-1 calendar, the insertion of Leap Year Days were suspended until either of the years 4 A.D. (757 UAC) or 8 A.D. (761 UAC) depending on the scholar and how many were already used prior to 8 B.C.
10. Outside of the problems with the frequency of leap year placements before 5 A.D., the modifications of the length of the months and other issues were identical.
11. The rules for the month lengths were the same as before.
12. Chances are, this calendar is not proleptic in nature, as there are no years with leap year days.
13. Four variations of this Julian-Roman-Transitional-1 calendar
1. Julian-Roman-Transitional-1 (aka Julian-Roman-Kalends-Transitional-1), days counting down to Nones, Ides and Kalends, and the year of reckoning is 753 B.C., the year Rome was founded. This was the original day counting direction/naming and year of reckoning that was intended to replace the Republican Calendar II in 45 B.C.E.
2. Julian-Kalends-Transitional-1 (aka Julian-Christ-Kalends-Transitional-1), days counting down to Nones, Ides and Kalends, and the year of reckoning is 1 B.C., the year Christ was conceived. This was conceived in the middle of the first millenium as it replaced the reckoning year of Rome.
3. Julian-Countup-Transitional-1 (aka Julian-Christ-Countup-Transitional-1), days counting up from 1 to the number representing end of the month, and the year of reckoning is 1 B.C., the year Christ was conceived. This is the standard since the middle ages.
4. Julian-Roman-Countup-Transitional-1 (aka Julian-Roman-Countup-Transitional-1), days counting up from 1 to the number representing end of the month, and the year of reckoning is 753 B.C., the year Rome was founded. I don't believe this calendar was ever used, but it's here for comparision with the other three calendar reckoning/day counting variations.
5. All four calendars above can be stretched backward to be proleptic.
