This odd calendar above is set as 30 days by 12 months cycle year. This equal as 360 days a year. Yet, we are not to rely on the exact 360 (or any pagan number such as 365, 355 or 383) days a years anyway. Stick with a simple YAH's appointed time system instruction. Understand why YAH's calendar time system follow by the sign of time such as the sun, moon, and stars. Knowing daytime and night cycle by the sun, season by season cycle by the moon and yearly cycle knowing by the stars’ movement. Knowing that 12 New Moon (Months) cycle equal a year. Some year might end up another month, because of the green early barley ear plants haven't yet appear for the spring season month.  We are only to count the first and seventh New Moon (month) cycle as appointed holiday, in order to track three feast festival appointed time of holidays. Other new moon cycle days are not the appointed holiday. To understand these methods, please obverse these calendar system along with the "YAH's Appointed Time Date" chart below.
