Contact Us

Email [email protected] for corrections, questions and permission requests. Email is the only way to reach us; the site has no contact form, phone line or account system.

Reporting a wrong date

To report a wrong date, email us the page address, the date you think is wrong and your source. We check federal holidays against the U.S. Office of Personnel Management (OPM) schedule, so an official link helps most. Corrections are fixed on every page and file that uses the date.

Commercial use requests

Email us which calendars you want, how many copies and how they will be used. Personal, classroom and internal business printing needs no permission; the printing license explains the details.

What happens to your email

We use your email only to reply to you. We don't add it to a mailing list or share it. The privacy policy has the full details.
