Quarter Moon New Years RE: [HASTRO-L] Conference: Living the Lunar Calendar

Dear Amos and Calendar People

You may remember that the 19-year cycle can be constructed out of years alternating between 49 and 50 quarter moons so that year 1 and 19 of the 19-year cycle each have 49 quarter moons.  Suppose you want the quarter-moon new year to always occur within Tishri and the quarter-moon 19-year cycle to start at the start of a lunar month, then it must start at year 12 of the Hebrew 19-year cycle. Then we have the quarter-moon new year occurring in the following quarters of Tishri:

12: Q1  13: Q2

14: Q4  15: Q1

16: Q3  17: Q4

18: Q2  19: Q3

01: Q1  02: Q2

03: Q4  04: Q1

05: Q3  06: Q4

06: Q2  08: Q3

09: Q1  10: Q2

11: Q4  12: Q1

All quarter-moon years that begin on the first quarter (12, 15, 01,  04,  09)  are preceded by a leap month year.

Hi Irv, it looks like a great opportunity to present your ideas about the Jewish calendar reform!

(Maybe other lunar calendars like Palmen's Yerms, might be of interest too)
