Fri, 10 Apr 2026 07:03:40 +0000 https://bugs.horde.org/ticket/7846 Sunbird displays recurring events one day short When I create an event that reoccurs every 1 week on Mo, Tu, We, Th, Fr till 01/30/08 from 08:00 till 19:00 the event will display one day short (till 01/29/08) in Sunbird. If I edit the event in Subird reselect the 01/30/08 and save again the event will be displayed correctly in Sunbird and Kronolith. When I then open the event in Kronolith again and just hit save, the event will be displayed again one day short in Sunbird.

Wed, 04 Feb 2009 22:16:12 +0000 https://bugs.horde.org/ticket/7846#t52283 The following event from my Horde calendar is one day short in Lightning as well as Outlook. The event starts on 14th April and is supposed to end on 17th April. In Lightning and Outlook the event ends on 16th April.

Mon, 30 Mar 2009 17:53:41 +0000 https://bugs.horde.org/ticket/7846#t53383 > Can you try version 2.3.1? I tried version 2.3.1 but the value of UNTIL is still output without the time. For example, Horde exports DTSTART:20090414T070000Z RRULE:FREQ=DAILY;INTERVAL=1;UNTIL=20090417 instead of DTSTART:20090414T070000Z RRULE:FREQ=DAILY;INTERVAL=1;UNTIL=20090417T070000Z This is the code from toRRule20() in Recurrence.php that outputs the date: if ($this->hasRecurEnd()) { $rrule .= ';UNTIL=' . $calendar->_exportDate($this->recurEnd); } As far as I can see the time in the final date should match the time from the event's start date. Mon, 30 Mar 2009 19:08:50 +0000 https://bugs.horde.org/ticket/7846#t53384 I think Sunbird and Outlook are wrong, because section 4.3.1 of RFC 2445 says: The UNTIL rule part defines a date-time value which bounds the recurrence rule in an inclusive manner. If the value specified by UNTIL is synchronized with the specified recurrence, this date or date-time becomes the last instance of the recurrence. If specified as a date-time value, then it MUST be specified in an UTC time format. If not present, and the COUNT rule part is also not present, the RRULE is considered to repeat forever. I interpret this as a date specified in the UNTIL part is inclusive. But since date-time values are allowed to and seem to work fine with both clients, I'm gonna use those.

After upgrading to your current sourcecode, the Recurring Event is displayed one day too often, as before. But this time, you manually add one day to "UNTIL". When I comment out that line, everything works fine with lightning. So changing kronoliths' recurrence.php in line 1168ff to: if ($this->hasRecurEnd()) { # $recurEnd = new Horde_Date($this->recurEnd); # $recurEnd->mday++; $rrule .= ';UNTIL=' . $calendar->_exportDateTime($this->recurEnd); } Works as expected again, leading me to the question, why you're adding an extra day to until.
