Three months from today's date (28 March 2013) will be 28 June 2013.
28 months = 852.2 days.
All months have at least 28 days
As today is January 11, the date 28 weeks and 6 days ago would have been June 23.
All 12 months have "at least" 28 days. Only February has exactly 28 days, except in leap year.
They all do because its saying how many months have 28 days not what months only have 28 days
All twelve months have at least 28 days, February has exactly 28 days except for leap years.
ALL months have 28 days! Should have said "Why does February have 28 days and some have 31?".
17 days later, which on today, June 11, would be June 28.
The only month that has 28 or 29 days is February.
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).
