About Gregorian Years
The Gregorian year = exactly 365.2425 days = 31,556,952 s (mean over the 400-year cycle with 97 leap years). The Julian calendar (45 BCE) used 365.25 days; Gregorian reform (1582) dropped 10 days and amended the centennial rule. Britain adopted it in 1752; Greece in 1923. Carbon-14 dates are reported in 'years BP' (before 1950 CE). 1 yr = 365.2425 d = 8,765.82 h = 31,556,952 s.
About Microseconds
A microsecond (µs) = 10⁻⁶ s; light travels ~300 m. Professional DSLR shutters reach 125 µs (1/8,000 s); electronic flash freezes motion in 1-50 µs. Radar pulse repetition intervals: 100-2,000 µs (15-300 km range). Ultrasound echo round-trips from 1-15 cm tissue depth: 13-200 µs. Muscle twitch contraction starts within 1-5 µs of the action potential. 1 µs = 10⁻⁶ s.
