Yes, it's correct - if you include both 7/16/99 and 2/22/22 - then, on Tuesday, 2/22/22, it's 22 years and 222 days since JFK Jr's removal from public view.

The computation page cited below explains in the notes that it includes the start date and excludes the end date. So you have to list 2/23/22 as the end date of the computation in order to have 2/22/22 included in the count
