I missed the stipulation that said not to include days that you lived in the property
A vast majority do miss that, as they don't read the small print.
(although I'm not sure what else would be considered personal use).
A personal use day would be any day you lived in the property as your primary residence, 2no home, vacation home, or any other type of "personal use", *after* you converted it to rental property. So if you lived in the home for say, 2 weeks for the primary purpose of performing repairs, maintenance, and/or property improvements, those days would not be personal use days.
