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.

Seconds

The second is the SI base unit of time, defined since 1967 as the duration of exactly 9,192,631,770 cycles of radiation from the caesium-133 atom. Atomic clocks based on this definition lose less than one second in 300 million years. The second underpins all timekeeping in modern civilisation — from GPS satellite synchronisation to internet protocols and financial transaction timestamps.
