To put year in perspective: Earth's orbit around the Sun (1 yr). In week, common references include a pay period (often 2 wk).
A tropical year (365.24219 days) is slightly shorter than the Julian calendar year (365.25 days) — the difference is why the Gregorian calendar skips leap years in most century years.
The 7-day week has no clean astronomical basis — unlike days, months, or years, it doesn't correspond to any natural cycle, and likely originates from ancient Babylonian or biblical tradition.
