About Minutes
A minute (min) = exactly 60 s, inherited from Babylonian sexagesimal astronomy. Medieval astronomers named the sixtieth part of a degree 'pars minuta prima' (hence minute); its sixtieth 'pars minuta secunda' (hence second). Running performance is expressed in min/km or min/mile; music tempo in BPM (beats per minute, ~40-220); angles in degrees-minutes-seconds (DMS). 1 min = 60 s = 1/60 h.
About Tropical Years
The tropical year = time from March equinox to the next = 365.24219 days = 31,556,925.2 s - the year that governs the seasons. The Gregorian 97/400 leap rule approximates it as 365.2425 days, leaving a residual drift of only ~26.8 s/year. The tropical year shortens ~0.53 s per century due to tidal deceleration. Persian Solar Hijri and Mayan Haab' calendars also approximate it. 1 a_trop ≈ 365.24219 d.
