Contact

The best way to reach us is email: joe@zona13.net.

What to include

• The page address (URL) of the tool.
• What you entered, the options you chose, what you got, and what you expected. A wrong result is easiest to check when we can repeat it with the same input.
• Your browser, operating system and the time zone your device is set to, because local times depend on them. If it is a date problem, say which zone and date.

There is no contact form on purpose: a form would mean collecting your data on a server. We read every email but cannot promise a response time.
