For the moment this is not easily done: it needs a new conditional tag to check if you’re viewing a single day and then show that day. Both have been implemented in trunk:
* Feature: for conditional tags, I added 1 extra shortcode:
#_IS_SINGLE_DAY (‘1’ if you’re viewing a single day, ‘0’ otherwise)
* Feature: new shortcode #_CALENDAR_DAY, returning the day being viewed when viewing a specific day on the calendar
So now in trunk, you can do this in the events list formatting setting:
[events_if tag='#_IS_SINGLE_DAY' value='1'] Events happening on #_CALENDAR_DAY [/events_if]
Now that I think of it, this should work too (in trunk):
[events_if tag='#ESC_CALENDAR_DAY' value='1'] Events happening on #_CALENDAR_DAY [/events_if]
