What Week: Week 6
Find the calendar dates covered by any ISO week number.
ISO Week 6 of 2026 runs from February 2 to February 8, 2026, with roughly 46 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. Groundhog Day, the Super Bowl fall within this week in 2026. Next year, 2027, the same week number runs from February 8 to February 14, 2027 instead, since the exact dates shift slightly every year.
