Week 10 of 2026 contains International Women's Day on March 8. 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 10 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 10 is the 10th Monday-to-Sunday block of 2026, which lands on March 2. All seven dates sit inside 2026, so the ISO year and the calendar year agree for this week.
