What is a day?
A day is 24 hours — the time it takes Earth to rotate once on its axis. It is the most common unit for planning trips, tracking deadlines, counting down to events, and measuring durations of a few days to a few weeks. Seven days make a week, and about 365 days make a year.
Days convert exactly to seconds, minutes, hours, and weeks. Converting days to months uses the 30.44-day average month, and days to years uses the 365.25-day Julian year to smooth out leap years.
