About these units
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.
Year (Leap) (y (leap))
A leap year contains 366 days, occurring roughly every four years in the Gregorian calendar to correct for the fact that a tropical year is not exactly 365 days. Leap years prevent seasonal drift by compensating for the extra 0.2422 days in each solar year. Without leap-year corrections, seasons would shift by one full day every four years, eventually placing summer in December over the course of centuries. Leap years are essential to maintaining synchrony between human calendars and Earth's orbital mechanics, illustrating how civil timekeeping must regularly adjust for astronomical reality.
