Note: The PHP date formats don’t natively allow for dots in am/pm (e.g., a.m. and p.m.), but for calendar events in LiveWhale you can choose to display them with dots by enabling <arg id="ampm_with_dots">true</arg> in your calendar widget settings.
If I understand it right, we set that up in calendar_widget.html file for individual group calendars? I did that in my Training calendar but it did not make a difference.
Yep, if you add that to your calendar’s <widget type="events_calendar"> settings block (often its in a theme file include called calendar_settings.html or calendar_widgets.html, but otherwise you can always start with /index.php and trace the file includes until you find where it’s referenced) you can add dots to those a.m./p.m. displays.
Or, you can use ENABLE_AP_STYLE=true site-wide which will make a handful of global changes to the calendar display as well as API and widget results: USE_AP_STYLE - LiveWhale Support
