Chatham Standard Time Zone facts for kids
The Chatham Standard Time Zone is a special way of telling time. It's used only on the Chatham Islands, which are part of New Zealand. This time zone is unique because it's set 12 hours and 45 minutes ahead of Coordinated Universal Time (UTC), which is like the world's main clock.

What is Chatham Standard Time?
Chatham Standard Time, often called CHAST, is the official time for the Chatham Islands. Imagine a clock that's 12 hours and 45 minutes faster than a global reference clock (UTC). That's how time works there!
Where are the Chatham Islands?
The Chatham Islands are a small group of islands far out in the South Pacific Ocean. They are located east of New Zealand's main islands. Because they are so far east, they are one of the first places in the world to see the new day.
What makes this time zone special?
Most time zones are set in full hours, like UTC+1 or UTC+8. Some are set in half-hours, like UTC+9:30. But the Chatham Standard Time Zone is one of only three places in the world that uses a 45-minute difference! The other two are Nepal Standard Time (UTC+05:45) and a less common time in parts of Western Australia (UTC+08:45). This makes the Chatham Islands' time zone quite rare and interesting.
What about Daylight Saving Time?
Just like many other places, the Chatham Islands also use Daylight Saving Time during their summer months. When this happens, clocks are moved forward by one hour. This new time is called Chatham Daylight Time (CHADT).
- CHADT is 13 hours and 45 minutes ahead of UTC.
- It's also 45 minutes ahead of New Zealand Daylight Time (NZDT).
Daylight Saving Time on the Chatham Islands usually starts on the last Sunday in September and ends on the first Sunday in April.
How is the time decided?
The time on the Chatham Islands isn't just a local choice. It's actually set by law! The New Zealand government passed a rule called the Time Act 1974. This law clearly states that the Chatham Islands' time must always be 45 minutes ahead of New Zealand's main time.
