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 Sidereal Months
The sidereal month = Moon's orbital period relative to the fixed stars = 27.3217 days = 2,360,591.6 s - the shortest lunar month. It is ~2.21 days shorter than the synodic month (29.53 d) because Earth advances ~27° along its orbit in the same period; the Moon must travel further to re-align with the Sun. Used in GPS orbit design, tidal modelling, and lunar laser ranging. 1 sid.mo = 27.3217 d.
