Our DC attend nursery four days a week, usually Monday to Wednesday. Sometimes I have to change days depending on work commitments and the nursery have always agreed to this. For the week after next I was going to ask tomorrow about swapping days so that DC attends Tuesday-Friday instead as I have work commitments and need to switch days.
If has now been announced that the Monday will be a bank holiday and the nursery will close on a bank holiday anyway.
Would if be unreasonable to ask if DC can attend Tuesday to Thursday when we are paying for four days but Monday they are closed anyway.
On the other hand, fees are averaged over the year so fees do not take into account this extra bank holiday.
