--- Comment #3 from Daniel Vrátil <dvra...@kde.org> --- Created attachment 163459 --> https://bugs.kde.org/attachment.cgi?id=163459&action=edit Screenshot from OpenSuse 15.5 Yes, 1st of November and 15th of November 2023, no occurence inbetween. I tried on Debian 11, OpenSuse Leap 15, KDE Neon (current stable) and recent git master, it looks as expected on all of them (see that attached screenshot from my OpenSuse VM). Does maybe the original event that you have in your calendar, have like a specific time, or a timezone? Maybe even different timezone than your system? What is your system timezone? Or is the original event an all-day event? What distro do you use? I can try to reproduce in a VM. Is the event stored in Google Calendar, CalDAV or local iCal file? The only cases I can imagine that could suddenly break the recurrence for one incidence are 1) accidental recurrence exception - maybe you accidentally moved the one occurrence from 1st to 8th, which created a recurrence exception (you can check in event editor -> Recurrence tab) 2) daylight saving time start/end in your or event's timezone somehow interfering with the recurrence rule, causing this odd miscalculation I can't think of anything else that could cause one calculation of the recurrence to suddenly go wrong on an arbitrary date and then resume correctly again. -- You are receiving this mail because: You are watching all bug changes.
