Termos de Uso

By using contardias.com , you agree to what is written here. These are simple rules, without complicated language.

This tool was created to help people accurately calculate deadlines and date ranges. We do our best to ensure the results are correct—holidays are updated, leap years are considered, and the business day logic has been tested. Even so, errors may exist. For legal, contractual, or financial deadlines with real consequences, always confirm the result with a qualified professional or the official source. The responsibility for the final decision always rests with the user.

The site is free and available for anyone to use. Copying the tool, redistributing the code, or using the site’s content commercially without prior authorization is not permitted.
