Days

The day is defined for civil timekeeping as exactly 86,400 seconds (24 hours). Two definitions coexist in astronomy: the solar day (averaging 86,400 seconds) and the sidereal day (approximately 86,164 seconds — 4 minutes shorter), as Earth must rotate slightly more than 360° to bring the Sun back to the same sky position due to its orbital motion. In medicine, the circadian rhythm operates on a near-24-hour cycle tightly coupled to the solar day.

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.
