The ISO Week Calendar tool is designed to provide a continuous view of weeks, making it easy to track and plan work schedules in industries such as manufacturing. This tool is based on the ISO-8601 standard, which defines a week as starting on Monday and ending on Sunday. This system is widely used globally, particularly in European countries, for its consistency and precision.

The ISO Week Calendar tool can be a valuable asset for manufacturing professionals in the following ways:

• Production Planning: Manufacturing teams can schedule production tasks based on ISO weeks, ensuring consistency and adherence to deadlines.
• Shift Management: The calendar makes it easier to assign and track shifts according to ISO weeks, which can be critical for meeting production targets.
• Logistics Coordination: ISO week numbers simplify coordination between departments and suppliers, ensuring timely delivery of materials and services.
• Reporting & Documentation: Having a uniform week numbering system ensures clear and standardized reporting across teams and departments.

The tool works by displaying the ISO Week Calendar for a specified month. The calendar includes the following features:

• Week Number Calculation: The tool automatically calculates the ISO week number based on the current date and displays it alongside the respective dates.
• Navigation: Users can easily switch between months, and the calendar will update with the correct ISO week numbers for the selected month.
• Highlighting Today’s Date: The calendar automatically highlights the current date, making it easy to track real-time progress in manufacturing operations.
• Week View: Each week is displayed with the start and end dates, making it clear which dates belong to which week.

This tool adheres to the ISO-8601 standard, which specifies the definition of weeks and their numbering system:

• ISO Week Start: The week always begins on Monday and ends on Sunday.
• Week Numbering: The first week of the year is the week containing the first Thursday of the year, ensuring that each year has exactly 52 or 53 weeks.
• Leap Year Adjustment: In a leap year, the calendar adjusts to ensure the correct calculation of weeks, including additional days at the end of the year.

The ISO Week Calendar tool uses the Majority Rule to assign weeks to specific months. This rule states that:

• A week is considered part of the month that contains the majority of its days. If more than half of the week’s days (4 or more) fall within a given month, the entire week is assigned to that month.
• For instance, if a week starts in December but most of the days fall in January, that week is considered to be part of January.
• This ensures that the week is properly aligned with the month where most of the workdays occur, providing clarity for production and scheduling purposes.
