Tuesday, August 1, 2028 falls in ISO week 31 of 2028. That week runs from Monday Monday, July 31, 2028 to Sunday Sunday, August 6, 2028, and it touches July and August. The ISO year 2028 has 52 weeks in total, so this is week 31 of 52, or about 60% of the way through the ISO year. 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. Schedules in manufacturing, logistics, education and project management are often written in week numbers, for example a delivery in week 31 or a sprint that ends in week 33. The week starts in 665 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. The week before is week 30, and the week after is week 32. The year pages list every week with its date range, and the week-number pages link to each of them.Which week is it?
