All 12 months have "at least" 28 days. Only February has exactly 28 days, except in leap year.
28 months = 852.2 days.
70 days is about 2 months plus 9 to 11 days, or about 2.3 average months of 30.4 days. A month can vary from 28 to 31 days.
They all do because its saying how many months have 28 days not what months only have 28 days
With a month being 28-31 days a 48 week period (336 days) would be approximately 11 months.
11 months have 29 days..........Only feb has 29 days in the leap year otherwise it has 28 days.
28 months = 852.2 days.
11 months have at least 30 days. Only one (February) has either 28 or 29 days.
70 days is about 2 months plus 9 to 11 days, or about 2.3 average months of 30.4 days. A month can vary from 28 to 31 days.
The riddle answer is "12" because all 12 months contain "at least" 28 days. February is the only month that has 28 days exactly, but 29 in a leap year.(The trick is that everyone says "1" because of this distinction. The version "If there are 7 months that have 31 days and 11 months that have 30 days, how many months have 28 days?" telegraphs the answer unless someone doesn't know how many months there are in total. So it is either erroneous or trivial.)

11. The question is not specifically asking how many months have "exactly" 30 days. 11 months have "at least" 30 days. There are four months that do have exactly 30 days, and there are at least five different versions of this riddle.
All twelve months have at least 28 days, February has exactly 28 days except for leap years.
852.23 days
Technically all 12 months have at least 28 days in them. However, I suspect you are actually asking how many months have only 28 days. In that case, February is the only month to have only 28 days in its month (except for leap year when it has 29 days).
February has 28 days
