Calendar 8:The Julian-Kalends-1 Calendar

Julian-Kalends-1 Calendar (calendar used from 532 A.D., Number Change Day on January 1)

The Julian-Kalends-1 calendar, based on the month formats of the revised Julian-Roman-1 calendar, uses the year of reckoning based on what was believed to be the conception year of Jesus Christ in 753 UAC or 1 B.C. (B.C.E.), rather than the year Rome was founded, and a version of the Julian calendar with the revised year of reckoning was introduced in the sixth century. The B.C./A.D. year dating system wasn't invented until then.

This can also be called the Julian-Christ-Kalends-1 calendar.

Dionysius Exiguus of Scythia Minor introduced the A.D. system in 525 A.D. (Anno Domini) (or 1285 UAC), counting the years since Christ was conceived. He began the revised Julian-Kalends-1 (or Julian-Christ-Kalends-1) calendar in the year 532 A.D. This calendar was gradually propagated for nearly 300 years until it was finally widely used after the year 800.

The last year of the old table, Diocletian 247, was immediately followed by the first year of his table, AD 532. When he devised his table, Julian calendar years were identified by naming the consuls who held office that year - he himself stated that the "present year" was "the consulship of Probus Junior", which was 525 years "since the incarnation of our Lord Jesus Christ".

There was no year zero in this calendar.

Special Days of Kals was in effect.

Leap year days were every four years, with the Leap Year Day still placed between VII Kal. and VI. Kal, or modern day Feb 23 and 24.

Number Change Day was January 1, hence the "-1" suffix.

1. Translating years between the Julian-Roman-1 and Julian-1 year examples:
1. The year 708 UAC = 46 B.C. (add 754 to the negative value of the number before the B.C. part to get UAC years)
2. The year 709 UAC = 45 B.C. (add 754 to the negative value of the number before the B.C. part to get UAC years)
3. The year 710 UAC = 44 B.C. (add 754 to the negative value of the number before the B.C. part to get UAC years)
4. The year 711 UAC = 43 B.C. (add 754 to the negative value of the number before the B.C. part to get UAC years)
5. The year 712 UAC = 42 B.C. (add 754 to the negative value of the number before the B.C. part to get UAC years)
6. The year 713 UAC = 41 B.C. (add 754 to the negative value of the number before the B.C. part to get UAC years)
7. The year 745 UAC = 9 B.C. (add 754 to the negative value of the number before the B.C. part to get UAC years)
8. The year 746 UAC = 8 B.C. (add 754 to the negative value of the number before the B.C. part to get UAC years)
9. The year 753 UAC = 1 B.C. (add 754 to the negative value of the number before the B.C. part to get UAC years)
10. The year 754 UAC = 1 A.D. (add 753 to get UAC years)
11. The year 757 UAC = 4 A.D. (add 753 to get UAC years)
12. The year 758 UAC = 5 A.D. (add 753 to get UAC years)
13. The year 761 UAC = 8 A.D. (add 753 to get UAC years)
14. The year 1285 UAC = 532 A.D. (add 753 to get UAC years)
2. Calendar Design:
1. the naming and length conventions were the same as those of the Julian-Roman-1 and Julian-Roman-Transitional-1 Calendars
2. Calendar naming from the Late Middle Ages (years unknown)
1. January -- 31 days
2. February -- 28 days (29 days in leap year).
3. March -- 31 days
4. April -- 30 days
5. May -- 31 days
6. June -- 30 days
7. July -- 31 days
8. August -- 31 days
9. September -- 30 days
10. October -- 31 days
11. November -- 30 days
12. December -- 31 days
