What Week: Week 44
Find the calendar dates covered by any ISO week number.
ISO Week 44 of 2026 runs from October 26 to November 1, 2026, spanning two calendar months, with roughly 8 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. Halloween, Dia de los Muertos, the End of Daylight Saving Time fall within this week in 2026. Next year, 2027, the same week number runs from November 1 to November 7, 2027 instead, since the exact dates shift slightly every year.
