Lunar/solar calendar intercalary months varied in name and precise length. However, seven extra lunar months were the chosen standard practice that matched with the seven-day week. The moon’s light divides in darkness according to seven-day periods for the four phases of the moon, and seven intercalary months divided lunar years from solar years in the 19-year cycle of the Jewish calendar. These early people had to know planting and harvesting times for the crops they raised in order to survive. Agriculture was the major source of food production for early culture. The Jewish Calendar’s Feast of First Fruits is one of the most celebrated worship festivals of the Bible. Linked to the Christian New Testament Pentecost, this celebration is a focal point for all Judeo-Christianity.
Feasts and festivals associated with farming in other cultures used a sacred-year. Agrarian societies often depended upon a sacred-year having 260-days. Intercalary days, a 360-day-civil-year, and the 260-day-sacred-year were integral to the calendars of early prehistory. These differing types of years were the common denominators for most lunar/solar calendars. Ancient calendar discovery begins with fundamental calendar tools.
The Sinai Peninsula holds the key to understanding past calendar systems. The Assyrians, Babylonians, Persians, early Egyptians and Israelites all used lunar/solar calendars. Common patterns are evident in early calendar versions. The foremost notion is evidence of a 360-day civil type of year. A 360-day length of year was the earliest form of the calendar, and the stem of Middle Eastern calendars. Five additional days were included to complete the solar year. The last five days were generally associated with religious festivities. Methods used to include the last five days of the full year were similar. Both Egyptian and Sun Kingdoms’ sister calendars intercalated five days each year. The sacred period of five-feast-days intercalates at the end of the year. A 360-day length of year was the basis for our modern 360-degree circle. Higher mathematics has paved the way to modern technology. lg 1.5 ton 5 star dual inverter split ac
The 360-day length of year was common in very early prehistory. For example, Hindu chronology once used a year of 360-days for historical computations. Generally, five-special-days then add to complete the solar year. Using 30-days for a month was common with the sun moving for six months or 180-days to the north, and for same number of days to the south. Ancient Persia used 360-days for a year, plus five supplementary days. The old Babylonian year, and the early Egyptian year, was composed of 360-days each. The Assyrian year also consisted of 360 days. Even the story of the flood reckons in 30-day months (Genesis 7:11 – 8:4).
360 Day Midpoint between Lunar/Solar Years
The concept of a time split calendar tool is actually very old. Lunar/solar calendars split time at the 360-day mark for every single 1-year. The ancient idea of God dividing daylight and darkness into day and night expands to God dividing “lunar-time” and “solar-time.” The lunar-side time split happened after twelve full lunar months. In whole numbers, another five or sometimes six-days were required to reach the 360-day midpoint length of year. The Mayan Calendar names the 360-day-calendar-year “Tun” (pronounced toon). My work with ancient calendars at timeemits.com applies hyphenated phrases such as 360-day-Tun-year to improve reading clarity.
