How many days in a month?How many days do you think are there in an average month? Think of an answer, before you proceed.
Ask anyone how many days in a month (I am not talking about specific months but in general) and the standard reply most often is 30 days.
Strange is it not that most of us remain ignorant to the fact that only 4 months in a year have 30 days and the rest have 31 days, with the exception of February, of course. Only April, June, September and November have 30 days, yet we remain oblivious to the fact, which is so obvious.
How many other apparent facts do we ignore? Can you identify any?
