This calendar has been updated for the Fall and Winter shows.
I was unable to find an updated iCal calendar on the web, so I created one myself and I'm sharing it with you. All you need to do is copy and paste this link into your calendar application. For example, from a MAC, go in iCalendar and click File > New Calendar Subscription and paste this link into that input field:
Public Calendar link:
You should now see the show dates with details populate on your calendar. I will try and keep this calendar updated should they add more dates this year. If you see something missing or off, please let me know in the comments.
