28 months = 852.2 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.)

They all do because its saying how many months have 28 days not what months only have 28 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).
