About Year (yr)
A unit of time corresponding to Earth's orbital period around the Sun, with several formal definitions depending on context: the Julian year used for unit conversions is exactly 365.25 days = 31,557,600 seconds per IAU 1976 definition; the tropical year (equinox to equinox) is 365.2422 days; the sidereal year (Earth's orbital period relative to distant stars) is 365.2564 days; the Gregorian civil year averages 365.2425 days per Pope Gregory XIII's 1582 reform (which inserted a 100/400-year leap-year correction to keep the calendar drift small over millennia — every 4th year is leap except century years not divisible by 400, so 2000 was leap but 1900 and 2100 are not). Practical applications: human lifespan (current global average 73 years per WHO 2024; US 78.4; Japan 84.3 per CDC NCHS Vital Statistics); ages and ISO 8601 date-of-birth notation; financial loan and bond terms (typical mortgage 15/30 years; corporate bond 1-30 years; US Treasury bonds 2-30 years); compound interest formulas A = P·(1+r/n)^(n·t) with t in years; warranty periods; climate-change projections per IPCC AR6 (2030/2050/2100 emissions pathway scenarios SSP1-1.9 to SSP5-8.5). Astronomical 'light-year' distance unit (9.461 × 10¹⁵ m) is derived from the Julian year.
About Millisecond (ms)
A unit of time equal to exactly 0.001 second = 10⁻³ s. Milliseconds are the native unit of computer performance and human-perception engineering: network latency per RFC 8312 + Google Network Quality (typical home broadband round-trip-time RTT 10-50 ms; transcontinental fiber RTT 60-90 ms; geostationary satellite RTT ~500-600 ms; Starlink LEO ~25-50 ms); page-load and TTFB (Time-To-First-Byte) per Core Web Vitals (Google PageSpeed Insights LCP target <2,500 ms; INP target <200 ms; CLS not time-based); display frame intervals (60 FPS = 16.67 ms/frame; 120 FPS = 8.33 ms; 240 FPS = 4.17 ms; 480 FPS = 2.08 ms competitive-gaming target); video-game input latency (competitive esports total system latency target <30 ms keyboard-to-photon per NVIDIA Reflex testing); HFT financial trading per SEC Reg NMS (NYSE matching engine matching latency ~30 microseconds = 0.03 ms; co-located HFT total round-trip 200-400 microseconds); human visual reaction time per Donders 1868 + modern psychophysics 200-300 ms simple visual stimulus, 400-600 ms choice reaction. The JavaScript Date API, Unix epoch with millisecond precision, performance.now(), and most performance profilers report in milliseconds by default.
