Your error is in the reference to c.start_time, c.end_time. During the
parse, the system doesn't know about "c" yet.
and swapping fortnight and "c" won't help - you can't reference
c.start_time in the "from" portion of the join.

So - substituting static values for c.start_time, c.end_time :
select * FROM generate_series('2016-01-22', '2017-12-31', '1
day'::interval) g(day)
left join generate_series('2015-01-25', '2016-07-01', '2
weeks'::interval) f(fortnight) ON g.day=f.fortnight

generates results... but I'm not sure it is giving you what you want.

Exactly what are you trying to achieve with the fortnight construct?
BTW - assuming call_schedule.start_time is a timestamp... do your
start/end times cross day boundaries? the test g.day between start/end
will never be true otherwise - you are dealing with "midnight" values
for time.
e.g. '2016-01-23' does not fall between '2016-01-23 08:30:01' and
"2016-01-23 10:45:01'
