What is the end of the year?
This counts down to midnight at the end of 31 December, the same instant that starts New Year's Day. It is the practical deadline for annual goals, calendar-year budgets, use-it-or-lose-it leave and anything that has to be filed before the books close. Tax years are a different matter and often do not line up: the United Kingdom runs to 5 April and Australia to 30 June, so check which year end you actually need before working to this one.
The next one falls on Thursday, 31 December 2026, and this page counts down to the midnight that ends 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.
