About Year (yr)
A unit of time corresponding roughly to Earth's orbital period around the Sun: approximately 365.25 days (31,556,952 seconds) in the Julian year commonly used for unit conversions. The Gregorian civil year averages 365.2425 days to keep calendar drift small over millennia. Years are the dominant unit for human lifespan, ages, loan and bond terms, compound interest, historical timelines, warranty periods, and climate-change projections. Astronomical "light-year" distances are derived from it.
About Hour (h)
A unit of time equal to 60 minutes or 3,600 seconds. Hours are the primary unit of human work and travel — business hours, flight durations, labor billing, and cooking times all use hours. The 24-hour day, divided since antiquity into 12 daylight and 12 nighttime hours, is preserved in modern 12-hour clocks and 24-hour military/ISO time notation. While not an SI base unit, the hour is accepted for use with SI and appears in countless derived units (km/h, kWh).
