How is the weekly number determined?

The week number is determined according to the ISO 8601 standard. All years have either 52 or 53 weeks. The first week of the year is the period of the week starting from Monday, of which more than half (ie at least four) of the days fall into that year. The first week of the year can therefore start on the side of the previous year. Similarly, the last week of the year can go into the next year.

What are week numbers needed for?

Week numbering is a way of indicating the time of year. Usually, the work is rhythmic according to the days of the week; the work week starts on Monday and the weekend is celebrated on Saturday and Sunday.
