What Week: Week 14
Find the calendar dates covered by any ISO week number.
ISO Week 14 of 2026 runs from March 30 to April 5, 2026, spanning two calendar months, with roughly 38 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. April Fools' Day, Easter, Good Friday, Passover fall within this week in 2026. Next year, 2027, the same week number runs from April 5 to April 11, 2027 instead, since the exact dates shift slightly every year.
