Is the end date included in the calculation?

Generally, no. The calculator measures the elapsed time boundary. If you need a "days covering" count (e.g., booking a hotel start to finish), you may need to add +1 to the days.

How many days are counted in a month?

The calculation uses actual calendar logic, meaning a month duration respects if a specific month has 28, 30, or 31 days.

Can I select a start date in the future?

Yes. The calculator works identically for past-to-past, past-to-future, and future-to-future date spans.
