About these units
Month (month)
A month traditionally reflects the lunar cycle, which lasts about 29.53 days (a synodic month). Ancient cultures used lunar months to track seasons, religious festivals, and agricultural cycles. In modern civil calendars, however, months are fixed lengths of 28–31 days to maintain alignment with the solar year. This creates a hybrid system: culturally grounded in the Moon, yet functionally tied to Earth's orbit around the Sun. Months remain one of the most intuitive time units for planning—budget cycles, billing periods, academic schedules, subscription systems, and medical dosing regimens all rely heavily on monthly intervals.
Minute (Sidereal) (min (sidereal))
A sidereal minute is 1/60 of a sidereal hour, lasting about 59.836 seconds in solar time. This unit refines astronomical timekeeping, enabling precise tracking of star transits, celestial navigation, and long-exposure astrophotography. Sidereal minutes illustrate how deeply astronomical timing differs from civil timekeeping, demonstrating the challenges of aligning human calendars with cosmic cycles.
