What dates are in week 48?

Week 48 of 2026 contains Thanksgiving Day on November 26. The seven dates always run Monday through Sunday, which is the part of ISO 8601 that most often catches people out: a week that starts on Sunday is a different convention and gives a different number.

How ISO week 48 is worked out

ISO 8601 fixes week one as the week containing the first Thursday of January, which is the same as saying the week containing 4 January, or the week holding the majority of its days in the new year. Counting forward from there, week 48 is the 48th Monday-to-Sunday block of 2026, which lands on November 23. All seven dates sit inside 2026, so the ISO year and the calendar year agree for this week.

When is week 48 in other years?

Week 48 shifts by a day or two each year because a year is 52 weeks plus one or two days, so the Monday that opens it moves from November 23 in 2026 to November 29 in 2027.

How far away is week 48?

Today is Wednesday, September 23, 2026, which sits in ISO week 39 of 2026. Week 48 of 2026 opens in 61 days, so there are roughly 9 weeks to go. Counting only complete weeks between now and then gives 8.
