About Week Numbers
Weeks in a Gregorian calendar year can be numbered for each year. This style of numbering is often used in European and Asian countries. It is less common in the U.S. and elsewhere.
The system for numbering weeks is the ISO week date system, which is included in ISO 8601. This system dictates that each week begins on a Monday and is associated with the year that contains that week's Thursday.
First week of year - Week W01
The first week is the week with the starting year's first Thursday in it (the formal ISO definition). There are some other definitions with the same result: The week with 4 January in it, the first week with the majority (four or more) of its days in the starting year or the week starting with the Monday in the period 29 December - 4 January.
Week 1 (W01) of 2023 goes from 2023-01-02 to 2023-01-08.
Last week of year - Week W52
28. December is always in the last week of its year. The week number can be described by counting the Thursdays: week 12 contains the 12th Thursday of the year.
Week 52 (W52) of 2023 goes from 2023-12-28 to 2024-01-03.
