Ancient calendars in the Holy Bible had lunar/solar calendar origins. The work at timeemits develops tools from the three oldest known lunar/solar calendars: Jewish, Mayan and Egyptian. Our goal here is to provide an overview that connects the Mayan calendar with the earliest Bible calendar -- the Antediluvian Patriarchs. Genesis 5 lists the ages of the Antediluvian Patriarchs. The “begat” family of Adam measured time with a lunar/solar calendar similar to the Mayan calendar.

The traditional Jewish lunar/solar calendar measures differences between the moon and sun to intercalate about 209-days over 19-years. Some 7-months add to catch up the lunar-side with the solar-side of the Jewish calendar. The Mayans adapted the same reasoning for a 20-year lunar/solar cycle and embed an extra 210-days using a different method. Some mystery and confusion exists surrounding the Mayan calendar. Hyphens help to improve phrase clarity.

The Mayan 52-year Calendar Round accomplishes needed intercalary time with a dual year system. The Mayan 260-day-Tzolken-sacred-year was part of a 365-day-solar-year. Alongside the 260-day-Tzolken-sacred-year, a 360-day-Tun-year kept track of civil functions. The 360-day-Tun-year marked the approximate middle point between 12-lunar-months or 354-days, and the 365-day-Haab-solar-year. Following the 260-day-Tzolken-sacred-year, 105-days more were included to finish the 365-day-Haab-solar-year. Sister cultures such as the Inca and Aztec used an identical system of counting. Earlier texts call them the Sun Kingdoms’ Calendars. Preference inclusively determines the name Mesoamerican Calendars.

Mayan astronomer-priests were very good at calculating multiples of days and years. Mayans purposely addressed a 360-day-Tun-civil-year with prefixes in order to lengthen the calendar. Prefixes are the “Katun” that describes 20-Tun-years and the “Baktun”, meaning 400-Tun-years. They multiplied the 20-year lunar/solar cycle by 20-years again, thus squaring time. Multiples of lunar/solar 20-year cycles occur in the form of 20-year-Katun-cycles and 400-year-Baktun-cycles. Mesoamerican chronologists accept the 400-year Baktun Cycle was an integral part of the Mayan calendar system.

The 365-day-Haab-year and 260-day-Tzolken-sacred-year combine to form the Mesoamerican 52-year cycle or Calendar Round. The 52-year chronological summit was the cornerstone of the dual calendar system. A complete Calendar Round repeated after 18,980-days. The Calendar Round 52-Tun-civil-years multiply by 360-days to produce 18,720-days. Working like meshed gears, 72-Tzolken-sacred-years of 260-days each multiply to equal the same 18,720-days. The last five special holidays are the Wayeb. The Wayeb separately accrues every year to add the final 260-days in the Calendar Round. One extra 260-day-Tzolken-sacred-year adds to 72-sacred-years for 73-Tzolken-sacred-years. Multiplying 73-Tzolken-sacred-years by 260-days per sacred-year gives the equivalent 18,980-days for a Calendar Round. The 52-year Calendar Round equals 73-Tzolken-sacred-years and both equal 18,980-days. The total 52-year Calendar Round is 18,980-days. By this calendar system, only once in 52-years would any day of the 260-day-Tzolken-sacred-year coincide with any day of the 360-day-Tun-civil-year. A complete 52-year Calendar Round would restart again the next dual sequence. Names for gods and their particular meanings often varied across the cultures. Calendar math remained the same.

We insert a fact from the Book of Enoch. Some ancient Jewish sects were using a 364-day calendar year. Information gained from the Dead Sea Scrolls and the three Book(s) of Enoch support the idea of numerical matching. This concept says X-number of days numerically match the same X number of years. A bridge forms between X-days and X-years, where X describes any number of days and years. The Mayan 260-year-Tzolken-sacred-cycle and the 105-year portion develop cascaded time.

All lunar/solar calendars are the product of prevailing culture. On the other side of the world, Mesopotamian scribes were recording Mayan calendar math in what we now call the Holy Bible. They were doubling and dividing calendar time with astonishing accuracy. The 260-day-Tzolken-sacred-year numerically matches a 260-year-Tzolken-sacred-cycle. A 365-day-Haab-solar-year numerically matches with 365-years in a Haab-solar-cycle. The 360-day-Tun-year likewise matches a 360-year-Tun-cycle.

Genesis 5:3

"And Adam lived an hundred and thirty years, and begat a son in his own likeness,
after his image; and called his name Seth:" (KJV)

Early Bible writers simply divided the 260-year-Tzolken-sacred-cycle in half to get the 130-year age of Adam. A few verses later, we have the principle calendar instrument of the Mayans, the 105-year age of Seth. Lunar/solar calendars distinguish between lunar-side times and solar-side times. The lunar/solar calendar effectively “time-split” 210-years into equal halves, a 105-year lunar-side time split and the opposite 105-year solar-side time split. These lunar/solar calendar tools enable us to comprehend mentioned ages for the Antediluvian Patriarchs.

Genesis 5:6

"And Seth lived an hundred and five years, and begat Enos:" (KJV)

Genesis 5:4

"And the days of Adam after he had begotten Seth were eight hundred years:
and he begat sons and daughters:" (KJV)

Suitable vocabulary is necessary to develop hyphenated names such as the 400-Year Baktun Cycle and 800-Year Generation Cycle. Twice the 400-Year Baktun Cycle measures one 800-Year Generation Cycle. Calendar references for the "begat" genealogy following Adam affix 800-Year Generation Cycles in repeating succession to each named character. From Adam through Jared, all Patriarchs include the 800-Year Generation Cycle. The Antediluvian Calendar cultivated spirituality of the planetary and star deities found woven into the oldest Mesopotamian cultures.
