Week 14 of 2026 runs March 30 to April 5

ISO week 14 of 2026 begins on Monday, March 30, 2026 and ends on Sunday, April 5, 2026. It has already passed; the current week is 39. The week covers the turn from March into April.

What dates are in week 14?

Week 14 of 2026 contains April Fools' Day on April 1. 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 14 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 14 is the 14th Monday-to-Sunday block of 2026, which lands on March 30. All seven dates sit inside 2026, so the ISO year and the calendar year agree for this week.

When is week 14 in other years?

Week 14 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 March 30 in 2026 to April 5 in 2027.

How far away is week 14?

Today is Wednesday, September 23, 2026, which sits in ISO week 39 of 2026. Week 14 of 2026 closed 171 days ago. The same week number in the following year is listed in the table above.
