If something happens twice a month it is called biweekly because it happens every other week and a month has 4 weeks. there is also bimonthly which is every other month but not really a direct word for something that happens twice a month.
It is probably anatomically possible, but you have something seriously wrong with you if that happens.
Do you mean bi-monthly? In which case, this would be referring to something that happens twice a month, usually once every two weeks.
Just as 12 is twice as much as 6, so too is 12 sets of something twice as many as 6 sets of the same thing. It matters not what that thing is. Think of a week as an example. It has seven days in it. 12 weeks is 12 sets of 7 days. 6 weeks is 6 sets of 7 days. 12 weeks is twice 6 weeks. So, if we calculate that 6 * 7 = 42 then we can calculate that 12 * 7 = 42 * 2 = 84.
