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 11 or a sprint that ends in week 13. The week began 210 days ago. 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."]],["Nearby weeks",["The week before is week 10, and the week after is week 12.
