Questions people ask
Which months have 31 days?
January, March, May, July, August, October and December have 31 days. April, June, September and November have 30, and February has 28, or 29 in a leap year.
Why are seasons opposite in the southern hemisphere?
Earth is tilted, so when the northern half leans toward the sun, the southern half leans away. July is summer in Chicago and winter in Sydney.
Which month is the shortest?
February, with 28 days in most years and 29 in a leap year. It is the only month that changes length.
Is each month equally likely?
Yes. The wheel has 12 equal slices, so every month has a one-in-12 chance no matter how many days it has.
