How ISO week numbers work

ISO 8601 weeks begin on Monday, and week 1 is the week that contains the first Thursday of the year. Because of that rule, the first days of January can belong to the last week of the previous year and the last days of December can belong to week 1 of the next. Most years have 52 weeks; roughly every five or six years a 53rd week is added to keep the count aligned with the seasons.

Planning by week

Schedules in manufacturing, logistics, education and project management are often written in week numbers, for example a delivery in week 46 or a sprint that ends in week 48. The week starts in 405 days, so there is time to plan. Keep in mind that US calendars often start the week on Sunday and use a different rule for week 1, so week numbers can differ between countries.
