The page tells you which week is currently in progress. The service is also connected to an annual calendar for the current year and currently also for the previous and two following years. The service also lists international and other days for celebration.
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.
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.
