[BUG]: Repeating events ignored if started 140 days previously

[NiccyB]

Describe the bug A repeating event is ignored if the original calendar entry is 140 days old or older. For example, on 1st May create an event that repeats every weekday forever. On September 18th, that calendar entry no longer triggers.

To Reproduce Steps to reproduce the behaviour:

1. Create a calendar entry and set it to repeat daily.
2. Wait
3. 140 days later, the calendar event no longer triggers daily.

Expected behaviour Calendar entries set to repeat should trigger on every occurrence of the repeated entry

Screenshots Calendar showing repeated entries: NodeRed showing that no trigger will occur until Saturday 23rd, ignoring the repeated entries in the calendar

Hey @NiccyB ,

I tried to reproduce your issue, as you can see below. But unfortunately it seems to work on my machine.... Can you please provide me some more informations? The content of the ics would be interesting. Perhaps privately per email [email protected]

Hi,

I'll post it below - there's nothing confidential in it. I have replaced the "Water" events in the calendar, but left the "Heat" ones in. In the following iCal, the first event listed (daily, M-F) stopped working on either the 17th or 18th September (i.e. the last time it triggered was either on the 16th or 17th), but the second event (Weekly, S-S) is still triggering.

I have tried the obvious stop/start/reboot.

The above is what Thunderbird dumps the calendar as. This is what Radicale presents:

Found another problem this morning when the house heating didn't turn on. There are repeating calendar entries which have been ignored for several days:

As you can see, the next trigger for 'Heating' and 'Water' are set for February 1st - both of these ignore the 30th and 31st January's repeats.

Note that the 'Heat' entry for today at 1000 was created today and the node has picked this up...

I can send the ics files separately if required.
