how many months of gap is allowed between 2 pg diploma courses

[William G]

Dear Friends,

If an individual is planning to do 1 + 1 diploma course, so how many months of gap is required to get a 3 yr PGWP.

A 8 months program has 4 months of vacations, so how many many months gap can an individual take to get a 3 yr PGWP

Thanks
