It would help to know for which table the clause entry is missing. I guess that the order of the joins is not correct:
left join generate_series(c.start_time, c.end_time, '2 weeks'::interval) f(fortnight) ON g.day=f.fortnight
LEFT JOIN call_schedule c on extract(dow from c.start_time) = extract(dow from g.day) AND f.fortnight IS NOT NULL AND
g.dayBETWEEN
c.start_time AND c.end_time
In the first line you use c, but this is declared on the following line.
