I'm using the calendar to post my group's games, but the date sometimes shows incorrectly.
I just posted a game for this Sunday, May 23rd. When I go to the calendar, the date shows correctly as May 23rd. However, when I look at Upcoming Events in my group, the date shows as Sunday, May 22nd.
This seems to happen fairly often. Sometimes the date shows correctly when I post it, later begins showing incorrectly, and then begins showing correctly again.
