In standard prose typing, you space twice after a period.
you space for a month....
You put the right quote immediately after the period and then 1 space.
Once. That is enough.
Two times
Normally two spaces indicates the end of a sentence.
If there is more than one initial, there is no space after the period which separates them. After the period after the last initial there is one space.e.g. T.S. EliotAfter a period at the end of a sentence you do two spaces, but often only one is done.
