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: US and ISO

In the US system, 2030 is divided into 53 numbered weeks. Week 1 starts on January 1, a Tuesday, and ends on the first Saturday of the year. Every following week runs from Sunday to Saturday, and the last week ends on December 31, so the first and last weeks can be shorter than seven days.

Under ISO 8601, 2030 has 52 weeks, each running from Monday to Sunday. ISO week 1 starts on Monday, December 31, 2029.

The next year with 53 ISO weeks is 2032.

Because ISO week 1 already starts on Monday, December 31, 2029, the last days of December belong to ISO week 1 of 2030, while in the US system they are still part of the old year.

Using the 2030 week numbers

The tables above show the start and end date of every week in both systems. That makes it easy to find the dates for a week number, for a delivery, a payroll period or a project deadline, whichever system your company or partner uses.

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