Does the tool count the start and end day?

Depends on the on-page option: some modes include both end-points, some exclude one. Read the hint; one day swings with the same two dates. Match your contract wording, not a guess.

Why do I need a day count between dates?

Contractual deadlines, warranties, net-30/60, travel, personal plans. Handy, not a lawyer. For disputes, read the clause, then the number.

How does NAP compute interest by day?

NAP has specific statutory interest and due-date rules, not this simple calendar differencer. Use the NAP interest page and the deadlines page on the site. Daily interest and start events live in a different model.

Are leap years counted?

Yes: Februaries in leap years have 29 days when the span crosses 29.02, so the difference is real, not a flat 365×years shortcut. The tool does not replace a bespoke “day” definition in a special contract.

Accordion answers; the same Q&A is in FAQ structured data for search engines.

You enter start and end; the app returns a calendar day difference according to whether the end is inclusive, as the UI says. This is not the working-day view. For Mon–Fri scoping, use the working-days tool.
