The Jewish calendar is based upon a 19-year lunar cycle. I went back in time 19 of these 19-year cycles to see which ones had prime numbered years. All cycles from the 286th to the 303rd had from one to five prime numbered years. The current 304th cycle: 5758 to 5776 is the only one not to have a prime numbered year.

 

There have been a total of 757 prime numbered Jewish years from 2 to 5749. 757 is the length of the short side of a golden rectangle drawn within the ‘Circle of Time’.

 

In the chart below the yellow rows are the Jewish leap years. Prime numbered years have a green background. Twin-prime pairs of years are enclosed within a box. There were no prime numbered years during the 13th year in each cycle. 13 is the first ‘Star of David’ number. 5770 is the last year in row 13. 5770 is a unique conjunction point between a row of years and column of 19-year cycles that do not have prime numbers. 5770 spans the majority of the Gregorian year 2010. 2010 is the range of the ‘Prime List’, the sum of the 4 corners of the ‘Prime Cube’, and the last year in the timeline: 1998 – 2001 – 2004 – 2007 – 2010. This timeline was derived from 3 unique Gregorian centenary leap-year exceptions and twin-prime clusters. Note: the 19th row in this chart does not have a prime numbered year, but if you go back to the very first cycle of 19 years the last year is 19 and 19 is a prime number.

 

There were a total of 43 prime numbered years during the last 19 cycles. George Walker Bush is the 43rd President. The last prime numbered Jewish year was 5749. Rosh Hashanah of 5749 was 12 September 1988. George Bush senior was elected President in 1988.
