Hi Rudolf,

unfortunately it's a bug in RRULE.js so we cannot fix it. I've reported it to Jakub Roztočil (RRULE.js main

developer), so we need to wait for a fix (it is really special case, and is related to not selected month in the

custom yearly repeat). 

Even if RRULE.js is not 100% perfect, it's much better than our old custom library, so I have no plan to remove

it from the upcoming release (even if that bug will be present).

I hope that we get a fix really soon, but I cannot guarantee that.

Cheers,

JM

Hello,

found one bug with recurring events. The following VCard is a copy'n'paste from Thunderbird's Lightning extension. In Lightning and the Apple OSX and iOS calendar apps this event appears correct at 08. February, beginnig at 1995. InfCloud show's this event at 08. AUGUST, even in the recursion details the February is shown correct. See screenshots:
