The lunar Sabbatarians are saying that in the Bible there are three months in a row that prove their calendar to be biblical and that prove the Gregorian calendar that we use today to be a fraud.
The calendar details of the three months in a row of the Exodus, the manna, and the mountain reveal divine lessons of the most vital and solemn importance. As often as these colorful stories are told and retold, their application of some details of time are often overlooked. In the first month (Abib), just prior to the Exodus, the heavenly Father, Yahuah, re-introduced His calendar. In the second month, He confirmed His calendar’s layout, and true seventh-day Sabbaths, in a most unmistakable way when He sent the manna from heaven. In the third month Yahuah, Elohiym, fully restored in the minds of all present, including the mixed multitude, His unique time-keeping system, with the date of Israel’s arrival at the famous desert Mountain of Sinai.

The modern Roman Gregorian calendar is not one and the same as that of Scripture, because it is an utter impossibility for it to have three consecutive months in a row that are identical. Specifically this means that because the weeks float throughout the months it is not possible to have the days of the week match the days of the month for three consecutive months. Exodus 12, 16, and 19 (Ibid., p. 7; accessed 12–30–13 at http://www.thecreatorscalendar.com/Articles/three_months/3_02_The_Mountain.html)
Most of them also say that the Sabbaths are always fixed on the eighth, the fifteenth, the twenty-second, and the twenty-ninth of each and every month.
The seventh-day Sabbath thus fell on every 8th, 15th, 22nd and 29th of the lunar month. (eLaine Vornholt and Laura Lee Vornholt-Jones, Time by Design, p. 9; accessed 12–30–13 at http://www.4angelspublications.com/articles/Time_by_Design.pdf)
Let us examine the scripture carefully to see if this is true. If the weekly Sabbaths are fixed on the eighth, the fifteenth, the twenty-second, and the twenty-ninth of each and every month, then God should have told it clearly in scripture. Out of the around 31,000 verses in the Bible, not a single verse talks about the seventh-day Sabbath being fixed on the eighth, the fifteenth, the twenty-second, or the twenty-ninth.
God clearly specifies many important days that are fixed to the dates of the month: the New moon God fixed on the first of every month, the Passover He fixed on the fourteenth of the first month, the Feast of Trumpets is fixed on the first day of the seventh month, the Day of Atonement is fixed on the tenth day of the seventh month, the Feast of the Unleavened Bread in the first month with two Sabbaths fixed (the fifteenth and twenty-first), and the Feast of Tabernacles in the seventh month with two Sabbaths fixed (the fifteenth and twenty-second).
If the weekly Sabbath is fixed on particular dates of the lunar month, why isn’t it specifically mentioned anywhere in scripture? Did God forget to mention the most important day?
The lunar Sabbatarians try to say to us that if Sabbath is fixed on Saturday, then where is it given in Scripture that the Sabbath is fixed on Saturdays? But how could the name Saturday appear in scripture, for the names of the days of the week were given by the Romans after the time period of the scriptures?! The lunar Sabbatarians cannot say this because ordinal numbers (first, second, third, etc.) are used as a method of identifying days in the Bible, from the beginning to the end, and not even in a single instance has God declared the eighth, the fifteenth, the twenty-second, or the twenty-ninth to be a fixed Sabbath!
In the Bible the word Sabbath or seventh (when in reference to a day) is mentioned close to one hundred seventy times, and out of these one hundred seventy references, the Scriptures do not identify the Sabbath with any date of the month, except in one or two instances. For someone to take these few instances and build a doctrine, when 98-99 % of scriptures on the same topic cannot be verified at all, is an unsound method of biblical interpretation.
For example, the time prophecies are amazing in their fulfillment. Consider this prophecy:
And it came to pass at the end of the four hundred and thirty years, even the selfsame day it came to pass, that all the hosts of the LORD went out from the land of Egypt. (Exodus 12:41)
This prophecy was fulfilled not only to the very year of prediction, but also to the very day! Do we, therefore, conclude that all time prophecies should be fulfilled in like manner?
We need to understand that an example may illustrate something, but it never defines anything. An instance of the Sabbath being kept on the eighth day of the month does not prove it was always kept on the eighth day of every month. Because there are a couple of instances where one can find a Sabbath on either the eighth, the fifteenth, the twenty-second, or the twenty-ninth day of the month does not prove that all Sabbaths of scripture must be on those dates.
