Cox (3-30-2021) http://code251.com/ The idea here is to align the Gregorian calendar with the 19-year lunar-solar calendar. TABLE 1 makes it obvious that the Gregorian dates, from the beginning of the Nabonassar calendar in 747 BC to the beginning of the Persian Hegira Era solar calendar in 622 AD, there are 1368 years (72 19-year cycles). There are twelve 19-year cycles in 228 years and eighteen 19-year cycles in 342 years. Every 1368 years, the Gregorian calendar dates of first new moons in the spring shrink four days, from 4/20 to 4/16.

During this lunar delay, 4/19 to 3/21, the lunar 19 years +19 +19 +19 +19 +19 switch from the latest date to the earliest date in the lunar 19 years, 4 15 4/12 4/13 4/13 4/14 4/15 which become earliest and latest boundaries in the 19-year cycle within -11 -11 -11 -11 -11 these two dates.

Whenever there is a solar eclipse on the equinox, on 3/20, the next 19 years have the same dates on the Gregorian calendar for next 19 years as it actually happened in 90, 71, 52 and 33 AD in TABLE 1 BELOW, and illustrated HERE. In TABLE 2: The Gregorian 365.2425-day calendar corrects the Julian 365.25-day calendar by omitting three leap days in years 100, 200, 300 out of every 400 years (The formula is 365 + ¼ - 3/400 = 365.2425). Correcting one day every 228 years (365 + ¼ -3/400 + 1/228 = 365.246886) is off one day in 7161 years against the 19-year calendar. Adding one day instead every 228 years is very accurate. To correct the lunar side, the 19-year lunar calendar needs to be delayed one intercalation (one moon of 29 days) every 342 years by switching from 4/19 to 3/21 during 18 of the 19-year cycles. There are 19 x 342 years in 6498 years, at which time one of the 29-day months disappears by running off the page and gets delayed out of existence. (The formula is 365 + ¼ -1/300 – 29/6498) After these corrections, the average solar day equals 365.2422038 days (off one day in 200,000 years). math gleaned from: https://www.friesian.com/calendar.htm#modern.
