I've used Trello for years but haven't needed due dates for my purposes until recently. Now I'm surprised to find that it seems to be impossible to add a due date as an all-day event. Events with times just get hidden in a calendar, and aren't useful for high-level planning.
Is there a way to do this? I have tried a couple of power-ups (eg. Planyway), but each had their issues, rarely work in all Trello clients, and in any case I don't want to set dates in a view separate from the main board/card.
