What is New Year's Eve?
New Year's Eve is 31 December, the final day of the year. The countdown here runs to midnight at the start of the 31st rather than to the midnight that ends it, so it reaches zero when the day begins and you still have the whole evening ahead. If you want the moment the year actually turns over, use the New Year's Day countdown instead. Because zones roll over one at a time, the first celebrations happen in Kiribati and the last in Baker Island.
The next one falls on Thursday, 31 December 2026, and this page counts down to the midnight that starts it in whatever time zone your browser reports. For a date of your own, the deadline countdown takes any target and tracks progress against it.
