Terms of use

By using timezonehistory.online you accept these terms.

What the site is

A free reference that republishes and analyses the public-domain IANA Time Zone Database. It is provided as is, without any guarantee that dates, offsets or calculations are complete, current or free of error.

No advice

Nothing on the site is legal, travel, scheduling or business advice. Clock changes after the date of the data release are calculations from the rules in that release and may not happen as shown.

Using the content

The underlying data is in the public domain. The site’s own text, charts and design belong to its operator, Blake Patterson; short quotations with a link are welcome.

Links

Links to other sites are given for reference; the site is not responsible for their content.
