What Week: Week 47
Find the calendar dates covered by any ISO week number.
ISO Week 47 of 2026 runs from November 16 to November 22, 2026, with roughly 5 ISO weeks remaining in the year after it. ISO 8601 weeks always run Monday through Sunday and belong to the year containing that week's Thursday, which is why the first few days of January sometimes belong to the final week of the previous year. No major U.S. holidays tracked by Dayswise fall within this specific week in 2026. Next year, 2027, the same week number runs from November 22 to November 28, 2027 instead, since the exact dates shift slightly every year.
