Is the date using 12:00:01 am?
Using the AdHoc Report module, I selected First Name, Last Name, and Registration Date From 5/16/16 to 5/16/16 to see who registered that day. Zero results.
Using Registration Date From 5/16/16 to 5/17/16, the results are ONLY the registrations from 5/16.
Using Registration Date From 5/16/16 to 5/18/16, the results are ONLY the registrations from 5/16 and 5/17.
Adding time to the date range would be awesome. I knew we had registrants that day so I continued experimenting with the report, otherwise I would have mistakenly thought we didn’t have anyone register that day. Adding time would also allow us to determine how effective a outreach event (say a school visit in the afternoon) was in capturing registrations.
Thanks for considering!
