How week numbers work
These follow the ISO 8601 standard used across Europe and in most business software: weeks run Monday to Sunday, and week 1 is the week containing the year's first Thursday. That's why a year has 52 or 53 weeks, and why the last days of December can belong to week 1 of the next year.
