Our Day Calculator tool can quickly give you the answer. To use it, follow these simple steps:
1 month is equivalent to:
The months are either 28, 29, 30, or 31 days long. The Gregorian calendar is made up of 12 months, each between 28 and 31 days long. Each month has either 28, 30, or 31 days during a common year, which has 365 days.
A calendar month may contain 28 to 31 calendar days; the average is 30.437. The synodic month, the interval from New Moon to New Moon, averages 29.531 d.
Are there 4 Weeks in a Month? All the months in the calendar have 4 complete weeks because every month has at least 28 days. A few months have some extra days, but they are not counted as a week because these extra days are not enough to sum up to 7 days. (1 week = 7 days).
Only four of our 12 months have exactly 30 days: April, June, September, and November. There are seven months with 31 days: January, March, May, July, August, October, and December. February is the oddball, with only 28 days, except in leap years when it has 29.
