FAQ
Common questions, clean answers
Does the date difference include both start and end dates?
This starter version calculates the elapsed day gap between the two selected dates. Inclusive counting can be added as an option later.
Can this be extended to business day logic?
Yes. The shared page structure allows a business-day variant to reuse most of the surrounding page and SEO content.
