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 hour?
An hour is a unit of time equal to 60 minutes or 3,600 seconds. There are 24 hours in a day. The hour originated in ancient Egypt, where day and night were each divided into 12 parts. The fixed 60-minute hour became standard only after mechanical clocks made equal hours practical.
Common uses of hours include: Work shifts and hourly wages; Travel and flight durations; TV schedules and event planning; Battery life and runtime ratings.
