Hi and thank you for this wonderful plugin!
I'm using the 5.5.2 version.
My WordPress is set +2 hours UTC. I have several recurring events that repeat every week, one day per week, starting from September and going until December 2013.
All of them jump one day backward (what was on Sunday goes back on Saturday and so on) after the daylight saving time change (on 27 of October). Not recurring events don't show up any problem.
You can see the problem on the calendar on the left: click here
