The sacred calendar is a central part of the true Gospel, because it determines the true Sabbath days, which are crucial signs of Yahweh (Ex. 31:13; Ezk. 20:12, 20). By these Sabbath signs Yahweh shows who He has personally sanctified. True, we are forgiven when we repent and accept the offering of Yahshua the Messiah (i.e. His sacrifice; Heb. 10:10). But the evidence that we are in fact sanctified by Yahweh is that we keep Yahweh’s true Sabbaths (See again Ex. 31:13; Ezk. 20:12, 20). The restoration of Yahweh’s calendar system is, therefore, a top priority of the International Congregation of Yahweh.

Most professing Christians have been lead to believe all they have to do is “believe” in the Messiah and their eternal life is assured; that all the “Old Testament” observances of holy days have been “done away.” Nothing could be further from the clear teachings of Scripture. “Belief” without obedience to the Law of Yahweh is contrary to the true Gospel Yahshua came preaching (Luke 6:46; Matt. 7:23). He said “Repent.” So we must know the Law before we can repent. Breaking that Law is sin. This includes the weekly and annual Sabbaths.

Until the latter part of the 20th century, the true Biblical calendar had been lost in antiquity. In its place, various civil and evangelical calendar schemes have been substituted over the centuries.

The Hebrew calendar is accepted by many as the true Scriptural calendar, which it is not. A copy of this calendar is found in “The Comprehensive Hebrew Calendar 1900-2000” by Arthur Spier (1952). In truth, the historical evidence shows beyond any reasonable doubt, the present Hebrew calendar is simply the ancient Babylonian calendar.

For example, the Hebrew calendar in use today uses the unscriptural Babylonian evening-to-evening day (or an equally unscriptural morning-to-morning day). It begins the month with the Babylonian first visible crescent of the moon following the conjunction. Although this is a widely used definition of the New Moon, among many religious groups, it has no Biblical basis whatever.

The true Biblical Calendar must be derived from the Bible itself – not tradition: “Sanctify them through thy truth; Thy word is truth” (John 17:17).
