How do I get my card to put a line through when I'm finished?

Even when I check complete, it doesn't put a line through it on calendar view.

Hi @Angela Loewen, Keli here with Trello's support team!

Right now, the Calendar View feature doesn't include a visual indicator that a due date has been completed. That's something that's on our radar!

Alternatively, the legacy Calendar Power-Up does show a visual indication, and once you check a due date as completed you'll see the card has a strike-through in the Calendar Power-Up. I hope this helps in the meantime.
