Knowledge of Creation handed down through the ages written by Moses, page 1

Genesis 18:14 Is any thing too hard for the Lord? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son.

Could this be a measured time in pregancy and birth such as the mayan 9 month calender. Seems like it to me. Proving they used a multi calender system. Life calender a solar calender a lunar calender so on and so on.

Exodus 2:23 And it came to pass in process of time, that the king of Egypt died: and the children of Israel sighed by reason of the bondage, and they cried, and their cry came up unto God by reason of the bondage.

Process of time is used many times in the bible when speaking of someones death.

Hebrew calendar

The Hebrew calendar (Hebrew: הלוח העברי‎ ha'luach ha'ivri) or Jewish calendar is a lunisolar calendar used by Jews, the followers of Judaism and in recent decades, by a growing number of Messianic Jews and Christians.

Lunisolar calendar

A lunisolar calendar is a calendar in many cultures whose date indicates both the moon phase and the time of the solar year. If the solar year is defined as a tropical year then a lunisolar calendar will give an indication of the season; if it is taken as a sidereal year then the calendar will predict the constellation near which the full moon may occur. Usually there is an additional requirement that the year have a whole number of months, in which case most years have 12 months but every second or third year has 13 months.

The Hebrew, Buddhist, Hellenic, Hindu lunisolar, Tibetan, Chinese (used alone until 1912 and then used along with the Gregorian), and Korean (used alone until 1894 and since used along with the Gregorian) calendars are all lunisolar, as was the Japanese calendar until 1873, the Hawaiian calendar, the pre-Islamic calendar, the republican Roman calendar until 45 BC (in fact earlier, because the synchronization to the moon was lost as well as the synchronization to the sun), the first century Gaulish Coligny calendar, the Byzantine Calendar, and the second millennium BC Babylonian calendar. The Chinese, Coligny and Hebrew[1] lunisolar calendars track more or less the tropical year whereas the Buddhist and Hindu lunisolar calendars track the sidereal year. Therefore, the first three give an idea of the seasons whereas the last two give an idea of the position among the constellations of the full moon. The Tibetan calendar was influenced by both the Chinese and Hindu calendars. The English also used a lunisolar calendar before their conversion to Christianity[citation needed].The twelve-month, thirty-day Hawaiian calendar incorporates the same sophisticated astronomy used by the ancient Polynesians to navigate throughout the Pacific and details when plants should be sown and fish caught. [2]

The Islamic calendar is a lunar, but not a lunisolar calendar because its date is not related to the sun. The Julian and Gregorian Calendars are solar, not lunisolar, because their dates do not indicate the moon phase — however, a lunisolar calendar is used in the determination of the Christian celebration of Easter..

So as you can see there was many calenders for them to use not one single calender.

Oldest lunar calendar identified

What could be the oldest lunar calendar ever created has been identified on the walls of the famous, prehistoric caves at Lascaux in France.

The interpretation that symbolic paintings, dating back 15,000 years, show the Moon going through its different phases comes from Dr Michael Rappenglueck, of the University of Munich.

The German researcher has previously associated patterns left in the caves with familiar stars and constellations.

He now says groups of dots and squares painted among representations of bulls, antelope and horses depict the 29-day cycle of the Earth's satellite

Isaiah 66:23 And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the LORD.

Even God gave a measurment of time as one full moon to the next.
