Ancient civilizations used the movement of heavens as celestial calendars.They created great stone monuments called as astronomical observatories to this end.To the ancients , an eclipse often presented the eyes of god,all seeing eye.
The lunar cycle was first discovered thousands of years ago by early civilizations who observed the repeating patterns of the moon's phases. Records of lunar observations date back to ancient civilizations such as the Babylonians, Egyptians, and Greeks.
All of them - ancient civilizations used to count full moon's to measure time. Every full moon is about a month.
The appearance of the moon two days ago would have depended on its phase in the lunar cycle. It could have been a waxing crescent, first quarter, waxing gibbous, or full moon, each displaying a different illuminated portion of its surface.
- Tracking the moon cycle with the calendar.A calendar synchronizes with the cycle of the sun or the moon. Many civilizations and societies have devised a calendar, usually derived from other calendars on which they model their systems, suited to their particular needs. A full calendar system has a different calendar date for every day. Thus the week cycle is by itself not a full calendar system; neither is a system to name the days within a year without a system for identifying the years.
Because of the regularity of the lunar phases. The Moon completes a cycle, from Full Moon to New Moon back to Full Moon in about 28 days. It was probably chosen as a marker for the passage of time based on observation of this regularity.
The moon will be a full moon, halfway through the lunar cycle.
On July 5, 2007, the moon was in the waning gibbousphase.Notice that 3 AM somewhere was occurring every hour for a 24-hour period, andthe one that was your 3 AM depended on your particular location on Earth.At 3 AM Central Daylight Time in the USA on that date, the moon was 80% illuminated,and waning.
The cycle of Venus is the same as the Moon's cycle.
The moon's cycle, known as the lunar month, lasts about 29.5 days. When the moon is halfway through its cycle, it is at the full moon phase, which occurs approximately 14 to 15 days after the new moon. Therefore, about 14 to 15 days pass when the moon is halfway through its cycle.
The first city states were probably the greek city states such as Athens, Sparta and Delphi. note: the city of Athens depended on trade and education the spartens depended on military and Delphi depened on religion
A full cycle - e.g., from full moon to full moon - is about 29 1/2 days. From new moon to full moon is half that time.A full cycle - e.g., from full moon to full moon - is about 29 1/2 days.

Circumstances that helped the civilizations and diverse cultures of the Americas to develop in ways both common and unique are the early civilizations of the Americas created such vast empires with an advanced form of thinking and living. These civilizations lacked some of the essential tools that the Asian civilizations depended on to form there amazing empires.
