The Standard time programme is replaced by the Summer time programme from 01/11/2020 to 01/02/2021. These dates are filled out automatically (unless the date has already passed before the override was created). The dates can be changed if the season looks a bit different.
The seasonal changes will happen automatically. This means that under normal situations, it should not be necessary to add a seasonal change programme. If you want to override a specific program with another one, AND seasonal overrides aren't set, this can be done here.
