Default calendar module seems to disregard month when filtering recurring events.

jpiatt

I have a very out-of-the-box installation of the default calendar module on my mirror. But the mirror’s calendar shows that my brother’s birthday is this coming Monday, which is March 23. However, my iCal (the one referenced in my config) correctly indicates my brother’s birthday is December 23. This seems to occur for all my yearly recurring events.

Anyone noticed this before? I’ve been running my mirror for a couple years now and I think this defect has been there for at least a year. I’ve just been too busy to look into it until now

Thanks in advance for any advice.

@jpiatt can you show the event from the iCal data

curl -sL the cal_url > somefile.txt

Edit somefile.txt and find the vevent for that

Paste here w code block around
You can change the title and any other thing that exposes you or your url. Don’t delete any lines

There is a big rewrite of the calendar processing coming on April 1.

You could test that now, see the troubleshooting section pinned topics on testing fixes

Thanks for your response. Below is the event from my calendar data. The result on the screen shows this event occurring on Monday (03/23/2026) when, as you can see the next occurrence is not until 12/23/2026.

@jpiatt because there are multiple vevents with the same UUID, AND NO rrule, this says the actual event has been expanded somewhere… are you using MMM-CalDav??

if so, please change the server side property

expand	true

to false
