About these units
Year (Tropical) (y (tropical))
The tropical year, about 365.24219 days, is the time it takes Earth to return to the same position relative to the vernal equinox. This is the year used to calibrate modern calendars because it governs the cycle of seasons. Precession of Earth's rotational axis causes slight variations in the tropical year, making it subtly different from the sidereal year. The tropical year is essential for determining solstices, equinoxes, and agricultural cycles. Modern calendar reform, leap-year algorithms, and astronomical computations rely heavily on this time unit. It reflects the delicate interaction between Earth's orbit and axial tilt.
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.
