ISO Week Numbers
It is recommended to use the “WI” week number fields as these represent the ISO week numbers.
ISO week numbers are commonly used in business systems.
Week One ISO can be defined as follows:
It is the first week with a majority (4 or more) of its days in January.
Its first day is the Monday nearest to 1 January.
It has 4 January in it. Hence the earliest possible first week extends from Monday 29 December (previous Gregorian year) to Sunday 4 January, the latest possible first week extends from Monday 4 January to Sunday 10 January.
It has the year's first working day in it, if Saturdays, Sundays and 1 January are not working days.
Therefore:
ISO Week 1 2022 starts on Monday 03/01/2022
ISO Week 1 2023 starts on Monday 02/01/2023
ISO Week 1 2024 starts on Monday 01/01/2024
