        I’m back with more calendar woes.

        I’m apparently still having an issue where events in my Outlook calendar can under certain circumstances not appear on my MM. This is again a symptom of the event’s rrule ending prior to the last event in the series. Some ICS code below:

        BEGIN:VCALENDAR
        METHOD:PUBLISH
        PRODID:Microsoft Exchange Server 2010
        VERSION:2.0
        X-WR-CALNAME:My Calendar
        BEGIN:VTIMEZONE
        TZID:GMT Standard Time
        BEGIN:STANDARD
        DTSTART:16010101T020000

        TZOFFSETTO:+0000
        RRULE:FREQ=YEARLY;INTERVAL=1;BYDAY=-1SU;BYMONTH=10
        END:STANDARD
        BEGIN:DAYLIGHT
        DTSTART:16010101T010000
        TZOFFSETFROM:+0000
        TZOFFSETTO:+0100
        RRULE:FREQ=YEARLY;INTERVAL=1;BYDAY=-1SU;BYMONTH=3
        END:DAYLIGHT
        END:VTIMEZONE
        BEGIN:VEVENT
        RRULE:FREQ=WEEKLY;UNTIL=20251007T164500Z;INTERVAL=1;BYDAY=TU;WKST=MO

        X-MICROSOFT-ISRESPONSEREQUESTED:FALSE
        END:VEVENT
        END:VCALENDAR
        

        I’m not sure if this is something that can be resolved, or why it happens but I suspect some timezone issue as I’m based in the UK and we have to endure changing the clocks twice a year.

        Having said that, the ICS file does not reflect the settings in the calendar for that event:

        be808da3-ff4d-4103-9307-66550f6a2838-image.png

        Anyone got any suggestions? Sorry to be a pest with this one!

          @WallysWellies the event looks correct according to the start/end and rrule
          But

          We do not use the custom timezone configuration in the iCal data
          We use the worldwide standard IANA tz names
          (Why one needs custom timezones is beyond me)

          Because so many users use MS products , I wrote a lookup table 5 years ago for the calendar parser we use, node-iCal

          But

          GMT Standard Time

          Is not in that table (GMT has long been replaced by UTC)

          UTC Standard Time

          Is in the table

          If the tz lookup fails, we use the local system timezone

              I don’t know why the rrule until says oct 08:164500, but oct 7 is the last Tuesday in the event cycle

              Sept 30 was excluded

              So all the iCal entry looks good except for the timezone

                @sdetweil the timezone on my Pi is:

                               Local time: Mon 2025-10-06 20:26:51 BST
                           Universal time: Mon 2025-10-06 19:26:51 UTC
                                 RTC time: Mon 2025-10-06 19:26:51
                                Time zone: Europe/London (BST, +0100)
                System clock synchronized: yes
                              NTP service: active
                          RTC in local TZ: no
                

                Is there something I need to do to try and resolve this? My MS calendar is set to a UTC timezone:

                    @sdetweil because Microsoft? Not really sure.

                    I’ve been digging into the iCal stuff and I see the windowsZones.json file which I presume does your MS to IANA mapping. In there is this line:

                    "GMT Standard Time":{"iana":["Europe/London"]}
                    

                    Is that what you were referring to - should this not replace the GMT timezone with the IANA equivalent? I’m just wading through code I only partially understand…!

                    I can ask a few people for sample icals to see if my GTM timezone is an oddity if that’s any use.

                      @WallysWellies can you add

                      stop MM

                      , "DEBUG"
                      

                      to the logLevel value in config.js at the top
                      and then start MM in debug mode

                      cd ~/MagicMirror
                      npm start >somefile.txt 2>&1
                      

                      wait til the calendar is up
                      then
                      ctrl-q on the MM screen to shut it down

                      then examine somefile.txt
                      (careful if posting, the debug log contains the full URL of the calendar from config.js)

                        I think this is the relevant entry from the log:

                          }
                        }]
                        

                        The timezone does look to be getting updated to the IANA string. But line 33 has:

                        "until": "2025-10-07T16:45:00.000Z",
                        

                        but the final event should be starting at 17:45 and ending at 18:30. So the ical does seem to imply that the series ends prior to the final event starting. Even if we account for the hour difference due to a potential timezone issue, the series is ending right as the final event starts.

                        Is there a particular part of the log that might be useful for digging deeper - a search string I can use to narrow things down? Or are we just looking at another Microsoft quirk…
