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.

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.
