I can not reproduce it using the C++ library on my unit tests. Looking at the saved event I noticed some problems.
This is an event saved by calendar app: BEGIN:VEVENT UID:20150611T123231Z-4234-1000-4111-1@rento-ubuntu DTSTAMP:20150611T123231Z DTSTART;VALUE=DATE:20150611 DTEND;VALUE=DATE:20150611 X-LIC-ERROR;X-LIC-ERRORTYPE=VALUE-PARSE-ERROR:Can't parse as RECUR value in RRULE property.

Create an all day event on 27th March 2015, move month view and the dot is against 26th March. Can be corrected by changing all day event to span 27th to 28th March but now event displays over two days on day view. Icon displays wrong date: next day date To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-calendar-app/+bug/1437305/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
