I know this sounds obvious, but I had a moment of understanding the other day – Calendar views and Gantt views have nothing to do with Calendar lists and Project lists!
They’re just views that happen to use date columns…
So you can configure the relationship between your list columns and the views…
That’s an interesting concept. We can use this with any list! For example, the start and end dates for help desk calls, or for displaying when things happened. Neat! I can’t think why I didn’t realise this before!
