About these units
Hour (Sidereal) (h (sidereal))
A sidereal hour is 1/24 of a sidereal day, approximately 59 minutes and 50.17 seconds of solar time. Astronomers use sidereal hours to measure right ascension and to coordinate telescope pointing systems. Because stars return to the same apparent position after exactly one sidereal day, sidereal hours offer a stable celestial reference frame. While not used in daily life, sidereal hours are indispensable for precision observation of the universe.
Fortnight (fortnight)
A fortnight is 14 days, a unit deeply rooted in English tradition. Its name derives from "fourteen nights," reflecting a time when day-to-day life was measured in nights rather than hours or minutes. Fortnights appear in literature, wage schedules, agricultural cycles, and even modern payroll systems in some countries. Though not part of the SI system, the fortnight persists because it occupies a natural middle ground: longer than a week, shorter than a month, yet easily divisible and memorable.
