Years

The year is based on Earth's orbital period around the Sun. The Julian year used in astronomy is exactly 365.25 days (31,557,600 seconds). The Gregorian calendar approximates the tropical year as 365.2425 days through its leap year rule, achieving accuracy to within 26 seconds per year. In geology, time spans are expressed in millions of years (Ma) or billions of years (Ga).

Weeks

The week is a unit of time equal to exactly seven days (604,800 seconds) with no direct astronomical basis. Its origin is cultural and religious, rooted in ancient Mesopotamian astronomy that associated each day with one of seven celestial bodies visible to the naked eye. The seven-day week spread globally through the Roman Empire and later through Christianity and Islam.
