Week 47 of 2026 runs November 16 to November 22

ISO week 47 of 2026 begins on Monday, November 16, 2026 and ends on Sunday, November 22, 2026. It starts in 54 days, about 8 weeks from the current week 39. The week covers November only.

What dates are in week 47?

No holiday or widely marked observance falls inside week 47 of 2026. 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 47 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 47 is the 47th Monday-to-Sunday block of 2026, which lands on November 16. All seven dates sit inside 2026, so the ISO year and the calendar year agree for this week.

When is week 47 in other years?

Week 47 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 16 in 2026 to November 22 in 2027.

How far away is week 47?

Today is Wednesday, September 23, 2026, which sits in ISO week 39 of 2026. Week 47 of 2026 opens in 54 days, so there are roughly 8 weeks to go. Counting only complete weeks between now and then gives 7.
