Written and maintained by DeadlineDaysReviewed on July 17, 2026

General use

DeadlineDays provides general date-planning information and should not be used as the only source for critical business decisions.

No professional advice

Calculator results do not replace legal, accounting, payroll, shipping, tax, employment, or contractual advice.

Site operation

DeadlineDays is an independent site built and maintained by one developer, working from South Korea. The developer is not a lawyer, employment specialist, accountant, or tax adviser. Because of that, the site publishes its calculation rules, holiday data sources, per-country verification dates, and known limits. Corrections: [email protected]

This statement describes the site's operating context and does not replace the responsibility to confirm any deadline against the contract, policy, official calendar, or service provider that governs it.

Free web-based calculators

DeadlineDays is provided as a free web-based set of business date calculators. Access may change as the site is improved, moved, or maintained.

No account relationship

Using the site does not create an account, advisory relationship, payroll service, tax service, shipping service, or professional engagement.

Your review responsibility

Users are responsible for reviewing calculator inputs, country settings, public holiday assumptions, and output before relying on a result.

No guarantee of accuracy

The site aims to be useful, but results are not guaranteed. Public holiday sources, regional observances, company rules, and service-provider schedules can differ.

Not professional advice

DeadlineDays is not legal, tax, payroll, accounting, employment, contract, or shipping carrier guarantee advice.

Appropriate use

Do not misuse the site, attempt to disrupt it, or treat generated dates as official deadlines without verifying them through the proper authority or contract.
