Weeks left in the year
The weeks, days, working days and weekends left until December 31.
How the weeks left are counted
The tool counts the days from tomorrow to December 31 in your time zone and divides them by 7. On November 10, 2026, for example, 51 days are left: 7 full weeks and 2 days, or 7.3 weeks.
Working days are Monday to Friday. Public holidays are not taken off, because they differ by country; the business days calculator counts working days between any two dates. A weekend counts as left while at least one of its two days is still to come.
The grid shows the weeks of the year by their week number: the weeks gone are faded, this week is highlighted and the ones still ahead stay solid. It is the same picture Left’s Year widget draws when you show the year in weeks.
Week numbers, and why some years have 53
The tool uses ISO 8601 week numbers, the standard in Europe and much of Asia. Weeks start on Monday, and week 1 is the week that contains the first Thursday of January. That makes most years 52 weeks long, but a year that starts on a Thursday, or a leap year that starts on a Wednesday, has 53.
Years with 53 weeks coming up: .
In the United States and some other countries, calendars often start weeks on Sunday and count the week of January 1 as week 1, so their week number can differ by one. The ISO week number tool finds the number for any date.
