About these units
Year (Sidereal) (y (sidereal))
A sidereal year is the time it takes Earth to complete one full orbit relative to distant fixed stars, lasting approximately 365.25636 days. This is the "true" orbital period of Earth in space, unaffected by precession-related shifts of the equinoxes. Sidereal years are used in celestial mechanics, spacecraft navigation, and modeling solar system dynamics. The slight difference between the tropical and sidereal year (about 20 minutes) reveals how Earth's wobbling axis alters how we perceive time, creating two distinct astronomical year definitions.
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.
