Calculated field for two custom date fields?
On a custom form, we have two custom date fields; one for an Event and one for a Digital Event. The digital event includes the time of day, while the event date does not (which is why we need two separate fields). I would like to create a calculated date field bringing in those two dates ("Calendar Date") so I can use the custom date feature on a calendar report. The team wants to see both Events and Digital Events together in one filter option.
I thought I could use the "or" expression of || between the two fields, but it doesn't look like that works.

Can anyone think of another way I should approach this so that I can get to one calculated date field?
