Hi Rogier,
I can't reproduce the issue.
When you write 

> Set custom repeat schedule of more then one day (2 or 3)

what do you mean exactly? Can you specify the settings you select in the Edit Recurrence dialog (for a _custom_ repeating rule)?
What version of Thunderbird and Lightning are you using?
Is the preference calendar.icaljs (Menu Tools > Options > Advanced > General > Config Editor) set to true or false?
Do you have errors in the Error Console (Menu Tools > Error Console)?
Do you use a local calendar or a remote one?

Note that the end date got repeated for 14 days more then I set it at.

Hey Decathlon,

See my attachments, hopefully that clears things up.

- Thunderbird: 38.5.1, but the issue has been around for much longer, just didn't get around to reporting it.
- Lightning: 4.0.5.2
- calendar.icaljs: false (default)

OK, a daily rule, not a "custom" rule. ;)

I've just installed the same versions of TB and LG but I can't reproduce on Win 7.

Could you please report:
- if there are errors related to the event in the Error Console (CTRL + Shift + J).
- if the calendar is local or remote;
- if you have others addons apart from Lightning on your Thunderbird. In this case, try to disable them and restart TB;
- try also to create a new profile and testing form there.

Your OS is Win 10, right?

Rogier, could you provide the information requested by Decathlon in Comment 5?

Hello,

I started writing up a reply last week, but then I noticed that with testing while writing I couldn't reproduce it consistently myself either.

In the specific case I encounter this issue regularly is when I create the task at the last week of the month, for the first tuesday/wednesday/thursday (at least two days) the next month. So my best guess now is that it has something to do with the time at which I create the task.

I will try to test it by changing my local date, but need to do that after work hours in the office so it might take a bit before I come back to this issue.

Sorry about that.

I think I managed to specify the thing that caused it, it only seems to happen when you create a new task by double clicking the events sidebar. I think it's called "Today Pane" officially?

About the other points
1. I get a warning, that's it:
Timestamp: 18-3-2016 15:53:07
Warning: Use of Mutation Events is deprecated. Use MutationObserver instead.
Source File: chrome://calendar/content/calendar-daypicker.xml
Line: 46
2. it's a remote caldav calendar
3. It's a freshly installed thunderbird because I wanted to rule out other issues, no other extensions.
4. See point 3.

By chance, when you create the event, do you change the start date proposed in the datepicker, by increasing it of a few/many days, and then (*after* that) you set the until date?
In this case it would be a consequence of bug 566149.
Can you reproduce the issue when you create the event without touching the start date?

Otherwise it might depend on the caldav server. You should enable the preferences calendar.debug.log and calendar.debug.log.verbose and take a look in the Error Console to see if there are errors or other info when you save the event.

The error "Use of Mutation Events is deprecated" is not related.

It doesn't happen if I don't change the start date, so it might be the same issue as you mentioned.

OK, thanks for the answer.
