Say no to the Gregorian calendar

This post intends to show that by no means does the current calendar that the world uses today match the biblical calendar prescribed by God. This knowledge is vital to those who arrive at the understanding that the appointed times within the scriptures are of critical importance.

Leviticus 10:1-2 describes the offering given to God by Nadab and Abihu outside of what God commanded and cost them their lives. The Most High doesn’t sway in the wind and demands what he commands.

1. And Nadab and Abihu, the sons of Aaron, took either of them his censer, and put fire therein, and put incense thereon, and offered strange fire before the LORD, which he commanded them not.
2. And there went out fire from the LORD, and devoured them, and they died before the LORD.

Leviticus 10:1-2 (KJV)

A brief history of the Roman calendars

The Gregorian calendar, first introduced in 1582 took more than 300 years for all the countries worldwide, give or take, to adopt, leaving the Julian calendar in the wake. It is also known as the Western or Christian Calendar and replaced the Julian Calendar because it did not correctly reflect the actual time it takes the earth to circle around the sun — known as the tropical year.

The Julian calendar was replaced because of the formula used to calculate leap years. The Julian calendar in itself was a reform of the Roman republican calendar.

By the 40s BCE, the Roman civic calendar was three months ahead of the solar calendar. Caesar, advised by the Alexandrian astronomer Sosigenes, introduced the Egyptian solar calendar, taking the length of the solar year as 365¼ days. The year was divided into 12 months, all of which had either 30 or 31 days except February, which contained 28 days in common (365 day) years and 29 in every fourth year (a leap year, of 366 days). Leap years repeated February 23; there was no February 29 in the Julian calendar. To align the civic and solar calendars, Caesar added days to 46 BCE, so that it contained 445 days. The calendar was not established in smooth operation until 8 CE.

Transitioning from the Julian to the Gregorian calendar required some days dropped to sync with astronomical events such as the vernal equinox or the winter solstice. The papal bull issued by Pope Gregory XIII in 1582 decreed that 10 days be dropped unless the switch occurred later which would result in more days being dropped.

Year of SwitchCountryDays Removed
1582France (most areas), Italy, Poland, Portugal, Spain10 days
1583Austria, Germany (Catholic states)10 days
1587Hungary10 days

1916Bulgaria13 days
1918Estonia, Russia13 days
1923Greece13 days
1926/1927Turkey13 days
The United States & Canada were British colonies which explains why they all transitioned at the same time.

The list includes only a small selection of countries. In some cases, it shows a simplified version of events. Countries are listed by their current names although their official name may have changed since the calendar reform.

The disqualification of the Gregorian calendar

Surprisingly the disqualification of the Gregorian calendar is easy as long as one is willing to do some basic investigation. Here are some reasons why the Gregorian calendar does not and could not possibly match the biblical calendar (keep in mind the foundation of scriptural timekeeping when trying to determine the validity of an argument for or against).

Reason 1

Transitioning from the Julian to the Gregorian calendar, several days were removed from the calendar. Considering the weekly seven-day cycle with the seventh-day being a Sabbath unless the number of days removed is a multiple of seven then that puts the Gregorian calendar out of sync with the biblical calendar.

8. Remember the sabbath day, to keep it holy.
9. Six days shalt thou labour, and do all thy work:
10. But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
11. For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.

Exodus 20:8-11 (KJV)

2. And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made.
3. And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.

Genesis 2:2-3 (KJV)

Reason 2

The Gregorian calendar transitioned from the Julian calendar which in turn is based on the Egyptian calendar that was transitioned from the Roman Civic/Republic calendar. Nowhere in this equation is the Hebrew calendar reckoned but rather to start with, a politically manipulated calendar in the Roman Civic calendar, and then a solar cycle based Egyptian calendar in that of the Julian and later the Gregorian calendar. The scriptural evidence suggests that the biblical calendar uses both the sun and the moon to determine time and date.

14.  And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:
15. And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.

Genesis 1:14-15 (KJV)

Reason 3

The Roman kingdom directly conquered the Grecian kingdom — not the Hebrew kingdom. This conquest of the Hebrew nation was a by-product of due to Israel already being under Grecian rule. There would be no reason to support a Hebrew calendar for a captured nation, which was one of many nations under Grecian rule. Previous to Grecian rule, the Persian and the Babylonian kingdoms rules over Israel. These rulerships can be seen in the four kingdoms of the book of Daniel.

Reason 4

The start of the Gregorian calendar year is January 1st with a repeating twelve-monthly cycle and seven-day weekly cycle. While the monthly and weekly cycle lengths are in-line with the Hebrew calendar, the start of the year, the length of the months, and the rolling week (this involves the continuation of the week from December 31st into January 1st) are not. These aspects of the Hebrew calendar are all explored in the scriptural calendar series.

Based on when the calendar started, that would establish the first day of the week. Since the two calendars begin on different dates, their weekly cycles would have to be synced unless they coincidentally matched. Even if there was such luck and they matched, they would be out of sync very soon for several reasons:

  • The rolling week of the Gregorian calendar opposes the fixed reset week at the start of the year of the Hebrew calendar
  • The beginning of the Hebrew year differs from year to year with the date of the Gregorian calendar.

1. Now the children of Israel after their number, to wit, the chief fathers and captains of thousands and hundreds, and their officers that served the king in any matter of the courses, which came in and went out month by month throughout all the months of the year, of every course were twenty and four thousand.
2. Over the first course for the first month was Jashobeam the son of Zabdiel: and in his course were twenty and four thousand.
3. Of the children of Perez was the chief of all the captains of the host for the first month.
4. And over the course of the second month was Dodai an Ahohite, and of his course was Mikloth also the ruler: in his course likewise were twenty and four thousand.
5. The third captain of the host for the third month was Benaiah the son of Jehoiada, a chief priest: and in his course were twenty and four thousand.
6. This is that Benaiah, who was mighty among the thirty, and above the thirty: and in his course was Ammizabad his son.
7. The fourth captain for the fourth month was Asahel the brother of Joab, and Zebadiah his son after him: and in his course were twenty and four thousand.
8. The fifth captain for the fifth month was Shamhuth the Izrahite: and in his course were twenty and four thousand.
9. The sixth captain for the sixth month was Ira the son of Ikkesh the Tekoite: and in his course were twenty and four thousand.
10. The seventh captain for the seventh month was Helez the Pelonite, of the children of Ephraim: and in his course were twenty and four thousand.
11. The eighth captain for the eighth month was Sibbecai the Hushathite, of the Zarhites: and in his course were twenty and four thousand.
12. The ninth captain for the ninth month was Abi-ezer the Anetothite, of the Benjamites: and in his course were twenty and four thousand.
13. The tenth captain for the tenth month was Maharai the Netophathite, of the Zarhites: and in his course were twenty and four thousand.
14. The eleventh captain for the eleventh month was Benaiah the Pirathonite, of the children of Ephraim: and in his course were twenty and four thousand.
15. The twelfth captain for the twelfth month was Heldai the Netophathite, of Othniel: and in his course were twenty and four thousand.

1 Chronicles 27:1-15 (KJV)

Reason 5

The premise that for anyone to start keeping the Sabbaths, feast days, new moons, etc. without having to be a scholar in calendar history is at the heart of the scriptural timekeeping. The sun, moon and stars are visible to everyone for signs and seasons — appointed times. God has pinned the appointed times, Sabbaths and feast days to the start of the year and the beginning of the months. We see this pinning in the Passover celebration being on the fourteenth day of the first month flies in direct opposition to the rolling week from year to year of the Gregorian calendar. If the Passover is pinned then consequently the Sabbath is pinned, which would make the Passover a Sabbath.

In the fourteenth day of the first month at even is the LORD’s passover.

Leviticus 23:5 (KJV)

This month shall be unto you the beginning of months: it shall be the first month of the year to you.

Exodus 12:2 (KJV)

Observe the month of Abib, and keep the passover unto the LORD thy God: for in the month of Abib the LORD thy God brought thee forth out of Egypt by night.

Deuteronomy 16:1 (KJV)
