How many weeks until Christmas?

12 weeks and 1 day

until Christmas Day, Friday 25 December 2026

That's 85 days in total.

It's Christmas Day

Whole weeks are counted from today, UK time, to midnight at the start of Christmas Day. The leftover days are shown separately, so on Christmas Eve this reads "0 weeks and 1 day". For the figure in days or sleeps, use the days until Christmas countdown.

When is Christmas 2026?

Christmas Day 2026 is on Friday 25 December, in ISO week 52. Boxing Day is a Saturday, so its bank holiday moves to Monday 28 December, giving most people in England and Wales a four-day weekend. Week 53 then runs from Monday 28 December to Sunday 3 January; check any week on the week number page.

Last posting dates and school holidays

Royal Mail had not published its last recommended posting dates for Christmas 2026 when this page was last checked on 1 October 2026. They usually appear in the autumn on the Royal Mail website, with earlier dates for international post than for UK 1st and 2nd Class. Lists already online that put 2nd Class on "Thursday 18 December" are last year's dates: 18 December 2026 is a Friday.

School Christmas holidays are set by each council or academy trust, so there is no single date. Most schools in England and Wales break up in the week before Christmas; the school term dates guide explains how to find yours.

More countdowns

Before Christmas come Halloween and Bonfire Night; after it, the New Year countdown. For the full list of bank holidays around the festive period, see UK bank holidays.
