Agent & API Discovery
DateSolver is a free, browser-based date and time calculator website. We publish a small set of public discovery documents so AI assistants, search agents, calculator agents, and browser agents can understand what the site offers and where to find authoritative metadata. Public calculator inputs stay in the user's browser — DateSolver does not expose a server-side calculator API or accept user-entered date inputs over the network.

Privacy
DateSolver calculators run in the visitor's browser. User-entered dates, birth dates, deadlines, and countdown dates are not sent to a DateSolver server, not logged, and not used for tracking. Agents should treat calculator inputs as user-local data unless an explicitly documented, authenticated DateSolver API says otherwise.
No protected public API
DateSolver does not publish a protected calculator API. We intentionally do not serve openid-configuration, oauth-authorization-server, or oauth-protected-resource metadata — there is no protected resource to authorize against. If you need a private integration or partnership, contact hello@date-solver.com.
