What is a recurring projection?

A projection is a faded item on your calendar: a forecast of a future occurrence of a repeating task or reminder.

They are shown so you can see which weeks are already spoken for. They cannot be opened, because there is no record behind them yet — a repeating task becomes real on its due date, and a repeating reminder becomes real once the current one is completed.

They can be switched off in the calendar filter, and that choice is remembered.
