What is a month?
A month here is the average Gregorian calendar month, equal to about 30.44 days (2,629,746 seconds) — one twelfth of an average year. The month originates from the lunar cycle (about 29.5 days), but calendar months were adjusted to fit the solar year. Because real months range from 28 to 31 days, an average length is used for conversions.
Common uses of months include: Loan and subscription billing; Rent and salary periods; Long-term project planning; Age and milestone tracking.
What is a week?
A week is a unit of time equal to 7 days or 604,800 seconds. The seven-day week has ancient roots in Babylonian astronomy and Jewish tradition, and unlike other calendar units it has no basis in astronomical cycles, running continuously for millennia.
Common uses of weeks include: Work and school scheduling; Pay periods and billing cycles; Pregnancy and gestation tracking; Project sprints and planning.
