The other five pages are comprised of three tables. The first, made up of 10x15 rows, has entries for 147 years (there are three blank boxes) from 1680 to 1826 (ú÷ôå). Under each year is a Hebrew letter, which is to be used in conjunction with the other tables. Two tables are for intercalculated years and two for years not requiring an adjustment, reflecting the fact that the Jewish year is lunisolar, and thus requires periodic adjustment so that the seasons and festivals remain relatively constant.
