According to Radio Times, General Hospital will air at the following times:

Monday to Friday
9.25am - 10.10am
1.05pm - 1.50pm
(I assume these will be the same episode or the early one may be a repeat of the previous day)


Sunday
9.45am - 1.35pm

It certainly looks like they will be the same episode, or as you say the 9:25 one will be a repeat of the previous days 1:05pm, as this would fit in with the omnibus on a sunday

Just looked at Radiotimes.com hoping they'd have an episode synopsis for Monday's show (so we might figured out where it starts episode wise), but its just a generic description
