Sun cycle meaning Earth cycle? Like what is used throughout the world today? Because someone is African American doesn't mean that they are on a different time schedule that anyone else. Please clarify what exactly you would like to know.
The Chinese developed the Chinese calendar and the Egyptian calendar, while the Hebrews developed the Hebrew calendar. These calendars were developed based on the cycles of the moon and the sun and were used for tracking time, religious observances, and agricultural purposes.
A liturgical calendar is used for religious purposes and divination and is usually based on lunar cycles. A regular calendar is used for civil or mundane purposes and is usually based on solar cycles.
As far as I know, all calendars that use lunar cycles start their months with the new moon.
The concept of counting years began with the development of calendars by ancient civilizations such as the Sumerians, Egyptians, and Babylonians around 3000 BCE. These early calendars were based on astronomical observations and cycles of the moon and sun.
Most modern calendars are based on solar cycles rather than lunar cycles because solar calendars align more closely with the Earth's orbit around the Sun, providing a stable framework for agricultural and seasonal activities. The Gregorian calendar, widely used today, is designed to keep the months and seasons synchronized, which is essential for planning and consistency. Lunar calendars, while accurate for tracking moon phases, can lead to significant seasonal drift when not adjusted to the solar year. Consequently, solar-based systems have become more practical and widely adopted for everyday use.
Many countries invented and used solar calendars, because it was one of the most apparent observable incidents in daily life. They became almost universal in one form or another. Modifications were introduced such as lunar calendars and joint solar/lunar calendars.
Calendars are based off of the solar system and how the Earth revolves around the sun.
Both the American and Chinese calendars are based on a solar system, with the American calendar following the Gregorian system and the Chinese calendar following the lunisolar system. They both have 12 months in a year, but the Chinese calendar has a leap month added every few years to make up for the discrepancy between lunar and solar cycles.
With the exception of the Julian day system, used primarily by astronomers, calendars are based on various inaccurate time periods given names such as year or month. Such periods are not of the same duration (length) as those used for scientific purposes.Most calendars are solar, lunar or luni-solar and are usually, but not always, synchronised with the sun or moon cycles.

Africans kept many customs and beliefs from their homelands. These customs and beliefs became the basis of African-American culture.
The Mesopotamian calendar, one of the earliest known calendars, was developed around 3000 BCE. It was based on lunar cycles, with months beginning with the sighting of the new moon. The calendar had 12 months, and to align it with the solar year, intercalary months were occasionally added. This system influenced later calendars in the region and beyond.
