How do I determine the number of parenting time days?

The simplest way to do it is by the number of nights they spend at the home of the non-primary parent. For example, if the schedule says Father gets every other weekend from Friday night to Sunday night plus two weeks of vacation each year. Then Father is getting two days every other weekend (as there are 52 weeks in a year, he gets 26 two-day weekends for a total of 52 days) plus the two-week vacation, which adds 14 days (but we presume two of those days would have been counted as his anyway, so we only add on 12 days). He gets a total of 64 days.
