Frequently asked
Are public holidays excluded?
Not yet — only weekends are excluded. A holiday-aware version is on the roadmap.
Are both endpoints counted?
Yes. If you'd prefer only days strictly between, subtract 1 from the result.
Does order matter?
No. Reversed dates return a negative count of the same magnitude.
