Advanced Search in the Contacts area, using the "date added" option and setting the date equal today.
There should be only one record there - a test case I added this morning. Instead, there are 801. Exporting the search results file shows that the filter doesn't look at the year or the month - only the day. All of the other 800 contacts were added on the 26th of a month - ANY month, any year. Sample below.
(Alas, this whole feedback/community thing is so confusing. I have no idea where to submit a simple bug report!)
