Terms of Service

ReckonDay's calculators are provided free of charge for general informational and planning purposes. While every tool is built on a unit-tested date-math engine and every effort is made to keep results accurate, ReckonDay is not a substitute for professional advice — legal, medical, financial, or otherwise — and results should be independently verified before being relied on for contractual, legal, payroll, or medical decisions.

The Sleep Calculator specifically is general wellness and scheduling guidance, not medical advice, and is not a diagnosis or treatment tool for insomnia or any other sleep disorder. Anyone with an ongoing sleep problem should consult a doctor.

Public holiday and calendar reference data is sourced from official government calendars as of the date noted on each relevant page and is reviewed on an annual cadence; holiday rules can change by legislation, and the most current official source for your jurisdiction should be consulted for anything time-sensitive or legally significant.

Paid products (such as the Life Calendar Report) are fulfilled as described on their respective product pages. Questions about an order or a purchase should be directed to contact@reckonday.com.

These terms may be updated from time to time; continued use of the site after an update constitutes acceptance of the revised terms.

ReckonDay's underlying date-math engine is unit-tested against a wide range of leap-year, month-end, and time-zone edge cases, but no software is free of the possibility of an undiscovered bug; if you believe a result is wrong, please report it via the Contact page rather than relying on it for a time-sensitive decision without independent verification.

All content on this site — including the reference pages, blog posts, and holiday tables — is provided for general informational purposes and may be shared or linked to freely; reproducing large portions of the site's written content elsewhere without attribution is not permitted. The underlying calculation logic and design are ReckonDay's own work and are not licensed for reuse in a competing product without prior written permission.

ReckonDay is not liable for decisions made based on a calculator's output, including but not limited to missed deadlines, scheduling conflicts, or financial outcomes resulting from reliance on a date or duration calculation. Users are responsible for independently verifying any result used for a legal, medical, financial, or otherwise consequential decision, particularly where the exact date or time carries contractual or regulatory weight.
