This table represents a week (read from left to right) with all the 24 hours marked and labelled by the planet which corresponds to them. We create this table by noting that the stars were created on Wednesday at twilight so we place Saturn (the first star) at hour 1 (or 6:00 p.m.). Then we follow with all the 6 other planets according to the geocentric model (Saturn, Jupiter, Mars, Sun, Venus, Mercury, and Moon).

Now we assume the world was created in the month of Nissan. So hour 1 on Wednesday on this chart represents the biginning of Tekufat Nissan (Spring). A solar year is 52 weeks and 1 day and 5 1/2 hours (according to the Talmud). This means that a year after creation Tekufat Nissan will occur 1 day and 5 1/2 hours later on the chart, or on Thursday between the 5th and 6th hours. Each year this will shift another day and 5 1/2 hours. How Long will it take for Tekufat Nissan to return to being on Wednesday at twilight? 28 years.
