What week is it?
It is ISO week 43 of 2026. See the current week number and how European (ISO 8601) week numbering works.
How ISO week numbers work
Most of Europe numbers its weeks with the ISO 8601 rule: weeks run Monday to Sunday, and week 1 is the one containing the first Thursday of the year — equivalently, the week that holds 4 January. A year has 52 or 53 such weeks. Because of this rule, the last days of December can belong to week 1 of the next year, and the first days of January can belong to the final week of the old one.

Frequently asked questions
What week number is it right now?
It is week 43 of 2026 under the ISO 8601 system.
How is the week number decided?
Under ISO 8601, weeks start on Monday and week 1 is the week that contains the year's first Thursday. That is why the first days of January sometimes fall in the last week of the previous year.
