Anthias Calendar showing events 2 weeks in advance

1

Wondering if anyone has advice, we have several raspberry pi’s with Anthias installed and acting as digital signage linked with google calendar. We have two events that are blocked out for a long period of time that is already showing up on the calendar, but the event isn’t for two more weeks on google calendar. I’ve tried updating and restarting the device, but it still thinks an event two weeks from now is going on.

If it helps, it is constantly re-updating itself for 1 minute blocks. For example a minute ago it said there was an event between 2:47 pm and 2:48. A minute passes and it updates again saying it’s between 2:48 and 2:49.

Any help would be appreciated, thank you.

@Terrarian, let me take a look at the issue closer.
In the meantime, I would like to ask a few questions:

  • What Raspberry Pi model are you using?
  • What’s the current Anthias version that you are using? (The version could be seen in the System Info page from the web UI)
  • Did the issue happen recently?

Sounds like Anthias might be mis‑reading the calendar data or your Pi’s internal time/refresh is off — double‑check that the Raspberry Pi model is supported, the Anthias version is up to date, and that the calendar event times & timezone match what Google Calendar shows. Asking those details helps pinpoint whether it’s a sync issue or a bug.geekprank.online

I should have responded here at the time of Nico’s response, I believe that the Anthias version was several versions out of date. After going through updating the software, they are all functioning as intended now. Thank you for responding to an older request though!

@king, yes, it would be better to check if the Pi’s clock is off or in sync. You could do so by running timedatectl:

               Local time: Mon 2026-03-09 15:54:15 UTC
           Universal time: Mon 2026-03-09 15:54:15 UTC
                 RTC time: Mon 2026-03-09 15:54:15
                Time zone: n/a (UTC, +0000)
System clock synchronized: yes
              NTP service: n/a
          RTC in local TZ: no

@Terrarian, thank you for sharing your updates. Glad that you’re not having the issue anymore. If similar or relevant issues happen, you could also try to specify query parameters that Google Calendar supports when embedding content.
