3-weekly whole day now shows Okt 23, but it should be Okt 22As I have seen in the calendar file, switching from DST to STD time is correctly defined for last Sunday in October, that is 25th of October. So this should not influence an event on 22nd of October…
Regarding events after switching from DST to STD time, I don’t have a clue, as I am not a dev, just a little experienced in testing…
I tried to understand the calendar file. As far as I have seen, you have only the date for whole day events (without any time):BEGIN:VEVENT
CREATED:20201001T205859Z
DTEND;VALUE=DATE:20201023
DTSTAMP:20201001T205900Z
DTSTART;VALUE=DATE:20201022
LAST-MODIFIED:20201001T205859Z
RRULE:FREQ=WEEKLY;INTERVAL=3;BYDAY=TH
SEQUENCE:1
SUMMARY:3-weekly whole day
UID:D718FE41-FF1B-43F6-9442-E9E43A41CCF0
URL;VALUE=URI:
END:VEVENTIn this case DTSTART is 20201022 and DTEND is 20201023.
For whole day events, can’t you simply set:
‘Begin’ to value of DTSTART 00:00 and
‘End’ to value of DTEND - 1day 23:59? (just as ical most probably uses 24:00 and that’s one day later)Maybe it’s not as simple as I assume, otherwise you would have tried that already…
As we currently have TZOFFSET+0200 and switch to TZOFFSET+0100, I would rather expect that we see current events (planned after 25th Oct) on the monitor 1 hour too late.
So that’s why I currently would rather expect:
Oct 27th 01:00 - Oct 28th 00:59 for weekly whole day after switching to STD time instead of
Oct 26th 23:00 - Oct 27th 22:59But as I mentioned before, maybe everything is much more complicated than I ever can imagine…

@SwissChemist your whole day event starts on one day, and ends on another
DTEND;VALUE=DATE:20201023
DTSTAMP:20201001T205900Z
DTSTART;VALUE=DATE:20201022make up your mind…lol
I changed all the whole day DTEND to the same date as the DTSTART
-
@SwissChemist if it were easy!!!
the rule processor has a bug w timezones
and apparently with multiple whole day events, and with dst/std adjustmentand the calendar parser is not ours, and the rule processor is not ours,
and we are split into get dates to show and show dates… show dates(calendar.js) doesn’t know anything about the cal entry. it’s just gets a list of start and end times, in utc time
-
I just uploaded another calendarfetcher.js to dropbox which corrects the timezone adjustment for daylight/std switch
I was using the local system time instead of the calendar event start time to compare offsets with the rule created time
-
I like how it behaves now… we are both currently on DST, you switch the daylight 1st (Oct 25), and the events when system is on my timezone, change, and then we change later to daylight (Nov 1), and then we are back on the same adjustment again and the event times adjust again correctly…

@sdetweil
Wow, that looks great! Thanks very much for your endurance!There is only that persistent ‘3-weekly whole day’ problem. It’s still one day too late. Most probably that’s so difficult, as it is a user defined interval, something strange seems to bring the parser to a wrong date…
For testing, I have added a 3-daily event. This shows correct start/end…But the rest is great! Thanks very much!!!
-
@SwissChemist check the end date in your cal entry it was set for the next day.
2 -day event
-
@sdetweil
All whole day events start at the right day and end one day later. There is no difference in the calendar file, whether it is a weekly, 2-weekly or 3-weekly event.
That’s why I do not understand, why weeklies and 2-weeklies are shown correctly and the 3-weekly is shown one day too late… -
@SwissChemist but, whole day events are defined as starting and ending on the SAME day.
-
@SwissChemist yeh, that 3-weekly whole day event seems to cause a problem in the rule handler…
for THAT rule, it returns the repeating day as the 1st of the 2, (the last of the 2 for the others)
but if u take off the ;BYDAY=TH
is works properly… (and gives the thrusday date)so, some bug in the rrule module… (not our code)
that is also the only weekly whole day rule you have which has a ByDay set.
