About Week (wk)
A unit of time equal to exactly 7 days = 604,800 seconds. The seven-day week has cultural and religious roots predating most other time units — appearing independently in: ancient Babylonian astronomy (named for the seven 'classical planets' visible to the naked eye — Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn — preserved in modern English Sunday/Monday/Saturday and Romance-language Mardi/Mercredi/etc.); Jewish religious tradition (Sabbath/Shabbat seventh-day rest per Torah Genesis 2:2 and Exodus 20:8-11); Roman planetary week formalized by Emperor Constantine in 321 CE; Islamic Hijri calendar (Friday Jumu'ah congregational prayer per Qur'an 62:9). ISO 8601 formalizes week-numbering (ISO weeks W01-W52/W53, starting Monday). Practical applications: pay periods (US bi-weekly 2-week cycle most common; UK monthly; ECMA-376 Office Open XML date formats include week-of-year); gestational age in obstetrics per ACOG + RCOG (full-term 37-42 weeks; preterm <37 weeks); software-development sprint cycles per Scrum framework (1-4 week sprints, 2-week most common); academic terms (quarter ~10 weeks, semester ~15-17 weeks per US Department of Education credit-hour definition). Not an SI unit and not officially accepted for use alongside SI, but the most widely recognized calendar unit on Earth.
About Hour (h)
A unit of time equal to exactly 60 minutes or 3,600 seconds. Hours are the primary unit of human work and travel: business hours and operating-hours signage, flight durations (FAA Part 121 / Part 135 commercial-flight operational limits in hours), professional billing rates (lawyers, consultants, contractors per BS 7000 / ISO 9001 service-billing conventions), labor regulations (US FLSA overtime threshold 40 h/week; EU Working Time Directive 48 h/week), and cooking times in recipes. The 24-hour day — divided since the Egyptian and Babylonian civilizations of antiquity into 12 daylight and 12 nighttime hours — is preserved in modern 12-hour clocks (US convention) and 24-hour military / ISO 8601 time notation (international scientific, aviation, and military convention; 14:30 ISO = 2:30 PM US). While not an SI base unit, the hour is officially accepted for use with the SI per the BIPM SI Brochure and appears in countless derived units (km/h vehicle speed, kWh electricity billing, m³/h industrial flow rates, BTU/h HVAC capacity).
