Most youtube videos show plaster being applied in 2 coats,

Can the second skim coat be applied a few days later ?

I've a big ceiling to do tomorrow and might get tired and clumsy after lifting up the first coat.

IME it may not stick.
So,
Wet down first coat with diluted PVA

A plasterer I know, where putting a skim onto old plaster, would paint
PVA onto the old and coat when still tacky.

Mix in PVA with second coat

Not hear of that.
