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.)
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- This short transistional calendar system is not to be used as a Proleptic calendar of any year of reckoning.
- The Julian-Roman-Transitional-1 Calendar is identical of the Julian-Roman-1 and Julian-Roman-Actual-1 Calendars with the following differences:
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- The rules for the month lengths were the same as before.
- Chances are, this calendar is not proleptic in nature, as there are no years with leap year days.
- Four variations of this Julian-Roman-Transitional-1 calendar
- 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.
- 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.
- 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.
- 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.
- All four calendars above can be stretched backward to be proleptic.
