Bit odd that Amy came home and her and Ken were talking about it being last day of term. It was mentioned that it was April 1st and she played a joke on Ken, so why didn't they realise when the filming was done that Easter was actually a week ago and there would have been no school.
They had Good Friday off and Easter Monday. Then 4 more days in school. Now off for one or two weeks depending on local authority. Those schools that broke up before Good Friday will find it's a long half term now until the next half term break. It's always a bit messy when Easter comes early
You may find differences between schools e.g. Catholic schools may differ. Some go back on Monday 4th April after having had only a week + Good Friday for Easter; some go back on 11th; others don't go back until 18th Apri.l
