Consider this sample file:

--------------------------------------------------
* Test with day of week

<2022-04-25 Mon 15:00>--<2022-04-26 Tue 02:00>

* Fails w/o DOW, end time at 2100 not 0200

<2022-04-28 21:00>--<2022-04-29 02:00>

--------------------------------------------------

Results in this agenda:

----------------------------------------------------------------------
Week-agenda (W17):

Saturday   30 April 2022
Sunday      1 May 2022
----------------------------------------------------------------------

So if the DOW is omitted from the end date, then it defaults to 24
hours?

I discovered this using gnus-icalendar to import ical invites. Gnus
appears to omit the DOW when creating the timestamp.

I thought DOW was optional in timestamps?

Confirmed.

The problem is that org-ts-regexp1 does not match "2022-04-29 02:00". I
am not sure why. org-ts-regexp1 looks like it should match the above
case. Maybe something to do with greedy/non-greedy regexp matching, but
its just a guess.

Best,

Is that technically a valid timestamp, meaning that it should be
recognized? Or is it just Gnus outputting a bad timestamp and I should
go try to adjust it?

It is valid. You can check it by calling M-: (org-element-context) at
timestamp. Our parser does recognise your example as:

(timestamp
 (:type active-range :raw-value "<2022-04-28 21:00>--<2022-04-29 02:00>" :year-start 2022 :month-start 4 :day-start 28 :hour-start 21 :minute-start 0 :year-end 2022 :month-end 4 :day-end 29 :hour-end 2 :minute-end 0 :begin 293 :end 331 :post-blank 0))

You can see that the end date is recognised correctly.

Best,
Ihor

What do you recommend as the next step?

org-ts-regexp1 should be fixed. But I currently have no ideas how. The
problem is caused by some edge case in Emacs regexp parser.
