· Talks about a "past in the future".
· We often use by with the future perfect (to mean at or before), e.g. by this afternoon, by the time we get there, by the time you've finished, by the end of the year, by then.

The form is:

+ have

· to say that something will end at (or before) a particular point in the future.

· to say what we think has almost certainly happed by now.
They'll have left by now. (I'm 99% sure they have left)

should (shouldn't)
+ have
+ past participle
· to show that we think something will happen before a certain point in the future (but are not 100% sure).
I should've finished by about six or so.
