Working days are the weekdays: Monday to Friday, excluding Saturday and Sunday. Public holidays are not subtracted here — a public holiday that falls on a weekday is still a working day by this definition, unless your employer treats it as a day off. If you need the count excluding holidays, that is the business day count: see business days in december 2026, which is 22.

How the count is worked out

Step one: count the days in the month — 31 for December 2026. Step two: count the weekends. December 2026 starts on a Tuesday, so the Saturdays and Sundays fall on the dates shown in the table — 8 weekend days in total, leaving 23 weekdays. Step three: there is none — working days are the weekdays, so the answer is 23. The days between dates calculator does the same calculation for any date range, and the date calculator works out what date it is a number of days from now.

December in other years in other years

The same month in the adjacent years, for comparison — the number changes because the calendar shifts by one day each year (two after a leap year), so the same month starts on a different weekday.

December 2026 in the year

December is the 12th month of 2026 — the 4th quarter of the year (Q4). There are 334 days in the year before December begins, and 0 days left in the year after it ends. In the Northern Hemisphere it is winter; in the Southern Hemisphere the seasons are reversed. 2026 is not a leap year, with 365 days.
