Calendar months don't align neatly with the Moon's actual orbital period (about 29.5 days) — they were adjusted historically, notably by the Romans, to fit a 365-day solar year evenly.
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.
