How to Build and Use a Horizontal Sundial to Determine the Spring Equinox

As stated in the books of 1 Enoch and Jubilees Almighty God's complete and perfect calendar has 364 days in a year which is exactly 52 weeks (52 weeks * 7 days/week = 364 days). All twelve months are 30 days each (12 * 30 = 360 days) and 4 intercalary days (season change days) occur at the end of months 3, 6, 9 and 12 (360 days + 4 days = 364 days) All dates on this calendar never change and are always on the same day number of the month and on the same weekday name. The last day of the year (day 364) on Almighty God's calendar is the Spring Equinox which is always on day 3 (Tuesday) of the week and the next day, day 4, (Wednesday) is the Head of the Year, day 1 of month 1. Therefore, it is very important to know the exact day when the Spring Equinox occurs which is when the sun crosses directly over the equator. This occurrence can be observed and proved by using a sundial because when the sun crosses over the equator the sun's shadow throughout the day will be a straight line west to east at any location on earth!
