Using ZenCountdown

ZenCountdown's tools are provided free of charge, "as is," for personal and professional use. We aim for accuracy but make no guarantee that results (including holiday dates and business-day calculations) are error-free or suitable for legal, contractual, or financial decisions — verify anything with real-world consequences independently.

No warranty

ZenCountdown is provided without warranties of any kind. We are not liable for decisions made based on calculator results.

Acceptable use

Don't attempt to disrupt the service, scrape it at abusive volume, or use it to generate spam content.

Changes

We may update these terms as the product evolves. Continued use after changes means you accept the current terms.
