**Steps to reproduce:**
1. Phorge at 81653abb5440109eb82c734d1671753a738dec3a, PHP 8.3.6 (`DateMalformedStringException` was [introduced in 8.3](https://www.php.net/manual/en/class.datemalformedstringexception.php))
2. Make sure Calendar prototype application is installed at http://phorge.localhost/applications/view/PhabricatorCalendarApplication/
3. Install `translations` extension via `git clone https://gerrit.wikimedia.org/r/phabricator/translations`
and following, make sure to use revision 8907cd5c6ad807732e5c5dc81a096f5114922d4d (as the offending strings were removed in https://gerrit.wikimedia.org/r/plugins/gitiles/phabricator/translations/+/094f99069cbae82366a9902ca5865b78cda02f78 ), and follow https://we.phorge.it/w/docs/extensions/install/
4. Enable http://phorge.localhost/config/edit/phabricator.developer-mode/
5. Set up calendar event `E9` called `abcdefgh` on some day from 11:00 AM to 5:00 PM
6. Keep `Time Format` as `Default` on http://phorge.localhost/settings/panel/datetime/
7. Set `Translation` to `Finnish` (which translates `AM` to `epp.`) on http://phorge.localhost/settings/panel/language/
8. Go to http://phorge.localhost/search/query/advanced/ , enter `abcdefgh` as the search term, set `Document Types` to `Event` and click `Search` button
**Expected outcome:**
Search results
**Actual outcome:**
```

**Other comments:**
* Phorge uses the localized AM/PM string for time format / comparison. The code should be made more robust by avoiding that.
* See https://phabricator.wikimedia.org/T363215#9741670 for gory details.
