Is the start date or end date included in the total days count?

The calculator counts the time interval (difference) between the two dates. If today is Monday and the target is Tuesday, the difference is exactly 1 day.

Can I find what date is 90 days from today?

Yes. Click the 'Add / Subtract Days' tab, keep today as the base date, select '+ Add', enter 90, and the exact future date and weekday will be calculated immediately.
