How do week numbers work?

Most of the world uses the ISO-8601 standard: weeks start on Monday and week 1 is the week with the first Thursday of the year. A year can therefore start in week 52 or 53 of the previous year.

Week numbers in 2030 explained

2030 has 52 weeks. The year starts on a Tuesday; only years that start on a Thursday, or leap years that start on a Wednesday, get a week 53. The next year with 53 weeks is 2032.

Week 1 of 2030 already starts on Monday, 31 December 2029. The last days of December therefore belong to the new year: if you note a week number on those days, it's week 1.

The last week of the year, week 52, ends on Sunday, 29 December 2030. Then week 1 of 2031 begins, a year with 52 weeks.

Using the 2030 week numbers

The table above shows the Monday each week starts on and the Sunday it ends on. That makes it easy to find the dates that go with a week number, for a delivery, a project milestone or a week of annual leave.

You can print all week numbers of 2030 or download them as an Excel or PDF file.
