What you get

How the Christmas countdown is calculated

Enter the date to count from — today is filled in by default. The calculator finds the next 25 December on or after that date and counts the calendar days remaining, reporting the days to go together with whole weeks and the weekdays (Monday to Friday) still to come.

★Method

Next 25 December, then a day count

If the counting date falls after 25 December, the target rolls forward to the following year’s Christmas Day. The count is a plain calendar difference, and both the whole-week figure and the weekday total are derived from that same day count.

◎Example

Worked example

Counting from Tuesday 20 October 2026, the next Christmas Day is Friday 25 December 2026: 66 days to go, which is 9 whole weeks, with 49 weekdays remaining.

⌁Limits

On the day itself

Count on 25 December itself and the result is 0 days to go; count on 26 December and the target has already rolled to 25 December 2027, 364 days away. The count uses whole calendar days, so the time of day never changes the number.

Common questions

Days Until Christmas Calculator FAQ

Answers about method, inputs, privacy, boundaries and responsible interpretation.

Which Christmas Day does the calculator count to?

The next 25 December on or after your counting date. Count at any point before Christmas and the target is this year's Christmas Day; count on 26 December and the target has already rolled forward to the following year's.

How many days are left from 20 October 2026?

66 days. Counting from Tuesday 20 October 2026, Christmas Day falls on Friday 25 December 2026, and the calculator also reports the wait as 9 whole weeks, with 49 weekdays still to come.

What does the calculator show on Christmas Day itself?

0 days to go. The count uses whole calendar days, so the time of day you check makes no difference to the number.

Why is the weekdays figure smaller than the days figure?

The weekdays total counts only the Monday-to-Friday days in the same span, leaving Saturdays and Sundays out. Both extra figures — whole weeks and weekdays — are derived from the same day count, so they always agree with the headline number.

Can I count from a date other than today?

Yes. Today is filled in by default, but the Counting from field accepts any date. Enter a different starting date and the calculator finds the first Christmas Day on or after it.
