The Table of Sixty-One Headings as a Tool for Finding the Intervals Between the Recurrence of Paired Year Codes in the Jewish Calendar

This paper presents an additional mathematical tool that can be used to analyze the Jewish calendar. The table of sixty-one headings was prepared in France, seven hun-dred and fifty years ago as a tool for finding the year codes for the 19-years of a par-ticular cycle of Jewish years. This unique table demonstrated that there are only 61 possible arrangements of the year codes in these 19 year cycles [1]. The table can be used to calculate the intervals between the appearances of a pair or any series of par-ticular year codes. These intervals create a closed path.
