This annoying “1” has appeared on the calendar icons on all my computers after updating to Mavericks.  It looks like the kind of thing that is intended to warn or notify me of something.  However, I haven’t been able to figure out what I am supposed to do.  Can you tell me what I need to do to make it go away?

The one on the calendar in the dock is letting you know that a date or event needs your attention in the main calendar. It could be an invitation or a reminder. Open your calendar on your mac and look in the top left corner. There should be a small symbol near the top left corner letting you know what the event is. By clicking that area, you’ll see what event wants your attention. Most of the time it is an invitation to a shared event between two people. After clicking it, you’ll be asked to accept the event or decline the event. After you’ve done that, the number should go away.
