ABOUT ISO 8601 WEEK NUMBERS:
Week numbers follow the international ISO 8601 standard, widely used in business worldwide. The first week of the year is the week containing the first Thursday, or equivalently, the week containing January 4th.
This standard ensures consistent week numbering across countries and organizations, making it ideal for:
• Business scheduling and planning
• Project timelines and milestones
• International team coordination
• Manufacturing and logistics
• Any work requiring precise week references
Note: Due to the ISO 8601 standard, years can have 52 or 53 weeks, and dates near year boundaries may belong to the previous or next year's week count.
