Is the start date counted?

No — counting starts the day after the start date and includes the end date, the convention used for most SLA and legal deadlines.

How do I add holidays?

List dates (YYYY-MM-DD, one per line) in the holidays box. Each listed weekday is removed from the count; weekend holidays change nothing since weekends are already excluded.
