About these units

Hour (h)

An hour, defined as 60 minutes or 3,600 seconds, is one of the most universally recognized time units. It emerged from ancient Egyptian timekeeping, where daylight was divided into 12 equal segments, a tradition that eventually influenced Greek and Roman clocks. The hour structures human activities: work schedules, travel planning, academic periods, medical dosing intervals, and astronomical observations. Its widespread adoption across cultures demonstrates the human tendency to organize life into consistent, predictable cycles. Even in scientific contexts where seconds dominate, the hour persists in fields like meteorology, orbital mechanics (e.g., solar time), and industrial processes. It bridges the gap between precise atomic time and everyday human experience.

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.
