What week 25 of 2026 means
ISO 8601 numbers weeks so every week starts on Monday and ends on Sunday. Week 1 is the one holding the year's first Thursday, which is why early January can land in week 52 or 53 of the previous year. Week 25 is one piece of that system.
In 2026, week 25 covers Jun 15 – Jun 21, 2026. That's June, deep in Q2. The same week number shifts by a day or two each year, so week 25 in 2027 won't share these exact dates. The table below shows how it moves.
Want to check a specific date instead of a week number? The week calculator converts any date to its ISO week. Curious how many weeks a year holds? The weeks in a year guide explains 52 versus 53. And the ISO week number page covers the standard end to end.
