How to construct God's Calendar and determine dates for the Holy Days:
Principles used in construction of the calendar to observe God’s Holy Days:
One: God says that the heavenly lights were given to determine seasons, days and years. These are heavenly objects which are observable without the need for any complicated instrumentation or technology. Gen 1:14 “…Then God said, ‘Let there be lights in the firmament of the heavens to divide the day from the night; and let them be for signs <226>, and seasons <4150>, and for days and years;’…” [NKJV].
Using Strong's Complete Word Study and given the context, this second part of verse 14 would be better rendered as follows: “…and let them be for seasons and signs <226>, and for the appointed feasts <4150>, and for days, and years:…”
NOTE: Nowhere in the Bible does it say that crops are to be used for the determination of seasons! God says that the lights in the heaven (sun and moon in particular) are to be used for the determination of the seasons – the instruction is very specific and there is no mention of crops. The early Hebrew calendar was faithful to this instruction, but the Jewish calendar incorrectly also uses crops as a determinant.
Two: Biblically, the year is divided into two parts – summer and winter (spring and autumn being added by man as transition periods) – with the March and September equinoxes marking the beginning and ending of these two major seasons. During an astronomical equinox, when the geometric centre of the sun is directly above Earth’s equator, the length of day and night can be significantly different. However, with an observed equinox the length of day and night are almost the same (equinox meaning equal night) and therefore can easily be determined by using a simple sundial. The Biblical evidence shows that simple solar and lunar observation is to be the method used in calculating the Hebrew Calendar dates and therefore it is considered that the "observable equinox" (when day and night are approximately the same length, using the appearance and disappearance of the solar disk) is a more appropriate measurement than the "astronomical equinox". This means the "observable" March equinox will fall on 16/17 March, NOT 20/21 March.
Three: Each month is to begin with the sighting of the first crescent of the new moon by the unaided eye – the Hebrew for month is "chodesh", with the root meaning of new thing. Using this method it is a simple thing to determine the 1st day of the 1st month (1 Abib – Ex 12:2). Modern astronomy has taken on the practise of calling the lunar conjunction the new moon, when it is darkest, but a dark moon cannot be seen (it is not observable) and therefore has not yet become something new. The new moon rises on the third night after it has died (become completely dark), so there is no real surprise when the annual Sabbath of 1 Ethanim (the 7th month – 1King 8:2) is to commence.

Four: Each new year begins on the first sighting of the new moon (small crescent) after the March equinox. There are some who begin the new year with the new moon closest to the March equinox even though it may be before the equinox. However, it is not considered reasonable to have the first month of the year begin before winter of the previous year has ended. Accordingly, even if the new moon is only one day before the equinox, that entire month belongs to the previous year.
Five: Each Biblical day begins at evening, not at midnight (Gregorian Calendar) and accordingly when a Roman day is cited, the intent is that the Biblical day commences the evening before. For example, the Roman day of 10 January will commence (Biblically) at sunset (evening) on 9 January.
Six: Sunrise and sunset are when the top of the solar disk first appears above horizon to start the day and when the top of the solar disk disappears below the horizon to start the night. As official equinox times are calculated using the geometric centre of the solar disk as it passes over the equator, rather than using equal length of day and night, there is about 5 days difference between an official (astronomical) equinox and an observed equinox (approximate equal observed length of day and night).
Seven: Currently, some elements associated with festival observance in Jerusalem are done through convenience rather than correct observance of the Word of God and therefore festival observances are not always on the correct days. However, as all festivals shall be coordinated with Jerusalem during the Millennium consistency with correctly calculated Jerusalem time is used for annual festival days (not weekly Sabbath times). If this were not done, then the nations would not consistently be able to go up to Jerusalem to observe the Feast of Tabernacles in the Millennium, as commanded by God. Zec 14:19 "...This shall be the punishment of Egypt, and the punishment of all nations that come not up to keep the feast of tabernacles..." [KJV]
Since God is consistent in all things it is reasonable to conclude that God expects His people to observe seasons and appointed times properly in this present day. Mal 3:6 "...For I am the LORD, I change not;..." [KJV]
Eight – Constellations: While the sun and moon were responsible for determination of the Hebrew Calendar and therefore responsible for determination of the annual Holy Days, in Job 38:31 there is evidence that the constellations played a role in identifying the type and duration of certain physical seasons of the year. The Pleiades appears to be mentioned in connection with the spring or vernal season, while Orion is mentioned in connection with the colder and less fruitful months of the year – in the northern hemisphere Orion may be seen in the morning, towards the end of October, and is visible through November, December, and January. The full meaning and use of constellations in agriculture, animal husbandry, fishing and hunting is not now clear, but it seems to be that they were intended to guide man in his physical survival activities throughout the year.
