Bug in the calendar

My calendar for October is showing 2 days as Oct. 17th, one for Saturday and another for Sunday (wrong!). If I click on the Sunday even if it’s labelled wrong, nothing happens. Unfortunately I can’t show the link to show the bug - “You have entered a link to a website that the administrator does not allow links to”. But if you want to try it’s ciclideosonline.com slash piwik.

Yes, this bug has been reported in another thread. It seems to be related to the rule changes in Daylight Savings Time. Since the calendar is generated on the client/browser, it probably requires an OS, library, or browser update.
