Q: What does the number in the red circle mean on calendar?
And how do I get rid of it? I would have guessed it's trying to show me there is some event today but it's been like this for a week and opening the calendar and scanning all the events doesn't make it go away.

It is a so-called "Badge app icon", notifying you of e.g. an invitation that someone sent you. So, you may check for invitations. Once accepted or denied, it'll be gone.
By default, it's the same as for the Mail or Messages icons: if something new has come in, you see the badge app icon, so you know without having the app open. Isn't it wonderful...?
You can enable or disable this for all app icons:
-> System Preferences -> Notifications, then select an app in the left pane (e.g. Calendar). In the right pane, (un-)check "Badge app icon" as per your liking.
