ISO 8601 numbering, used across Europe and most of Asia. The US often counts from the week of January 1 instead.
What is this?
ISO 8601 is the international standard: weeks run Monday to Sunday, and week 1 is the week that contains the year's first Thursday. Most of Europe and Asia use it for planning, payroll and logistics.
