How to use this week
This week page is useful when you need a direct link to a specific date range. You can use it in project plans, reports, school schedules, travel planning or recurring reminders. Because the page includes both the week number and the start and end dates, it is clearer than sharing only a week number.
When using week numbers in business documents, include the ISO year as well as the week number. This avoids confusion around New Year, when the ISO week-year can differ from the calendar year printed on the date.
