That week runs from Monday Monday, November 29, 2027 to Sunday Sunday, December 5, 2027, and it touches November and December. The ISO year 2027 has 52 weeks in total, so this is week 48 of 52, or about 92% of the way through the ISO year."]],["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 48 or a sprint that ends in week 50. The week starts in 420 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."]],["Nearby weeks",["The week before is week 47, and the week after is week 49.
