How to show what day of the week a meeting invite is on

When I receive a meeting invite, the email shows me the day and time of said meeting. However, I don't know what day of the week a day falls on. Let me expand on this point with the information from the picture below.

I was sent a meeting invite for April 20th at 12:00 PM to 2:00 PM. I don't know what day of the week April 20th is off the top of my head. 

I know I can just double click on the meeting invite in the calendar preview to find that information, but I'd like to know if there is a way to show the day of the week without having to do that.
