The months that have 31 days are: January, March, May, July, August, October and December.
If by "only 31 days" you mean "exactly 31 days", then 7. If by "only 31 days" you mean "not more than 31 days" then all of them.
In the order they appear through the year, the months that have 31 days are:JanuaryMarchMayJulyAugustOctoberDecember
All 12 months have "at least" 28 days. Only February has exactly 28 days, except in leap year.
In a leap year, there are 186 days in the 31 day months and 180 days in the other months, so that is a difference of 6 days.
There are 30+31+30+31 = 122 days in the last four months of the year.
11 months have 29 days..........Only feb has 29 days in the leap year otherwise it has 28 days.
233 days is about 7.65 months. (average months, or about 7 months, 20 days) It is only possible to estimate here as the months of the year have either 28, 30 or 31 days, then there is a leap month which has 29 days.
212 days in a normal year and 213 days in a leap year.

In a leap year, a day is added to February to keep the balance of the calendar making the year have 366 days in the year instead of 365. The number of days in all the other months stay the same which means that the months with 31 days stay the same. The months with 31 days are January, March, May, July, August, October, and December adding up to 7 months.
I believe... 12 months. On the calendar there are 12 months, one year. A calendar year. a calendar year consists of 365 and a quarter days. it is divided into 12 months. there are 52 weeks in a calendar year each week has the following days - Sunday, monday, Tuesday, Wednesday, Thursday, Friday, Saturday. January - 31 days february - 28 days (29 in a leap year) march - 31 days April - 30 days may - 31 days June - 30 days July - 31 days august - 31 days September- 30 days october - 31 days November - 30 days December - 31 days
31+31+30+31+30+31 = 184 days in total.
