Generally, I myself do a day count. Five years back from the closing date of the sale will have "at least" one leap year in it. So that's 1826 days. (the closing date of the sale does not count as a day for anything.)
So if it was your primary residence for at least 731 days of the last 1826 days you owned it, there's no need to get picky about move in/out dates.
Bottom line is, when using TurboTax the program will "know" based on the dates you enter, if you qualify or not. Either you do, or you don't. Period.
