About these units
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.
Septennial (7 years)
A septennial period spans seven years and historically appears in legal, agricultural, and religious cycles. In medieval Europe, land leases, debts, and apprenticeship terms sometimes lasted seven years. Biblical traditions also emphasize cycles of seven, including sabbatical years. Modern risk analysis, demographic studies, and financial planning sometimes examine seven-year spans because they capture medium-term trends while avoiding short-term volatility.
