No holiday or widely marked observance falls inside week 26 of 2026. 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 26 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 26 is the 26th Monday-to-Sunday block of 2026, which lands on June 22. All seven dates sit inside 2026, so the ISO year and the calendar year agree for this week.
When is week 26 in other years?
| Year | Monday | Sunday | Weeks in year |

Week 26 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 June 22 in 2026 to June 28 in 2027.
