ISO and U.S. week numbers

Two systems are in common use, and they can disagree by one around New Year.

ISO 8601, used in business and most of Europe: weeks start on Monday, and week 1 is the week with the year’s first Thursday.
U.S. calendars: weeks start on Sunday, and week 1 is the week containing January 1, even if it’s only a day or two long.

So Friday, January 1, 2027 is in ISO week 53 of 2026 but U.S. week 1 of 2027.

Why some years have 53 weeks

A year is 52 weeks plus a day (two in a leap year). When a year starts on a Thursday, or on a Wednesday in a leap year, that spare day pushes the ISO calendar to 53 weeks. 2026 starts on a Thursday, so its week 53 runs from December 28, 2026 to January 3, 2027. The next 53-week year is 2032.

Working out the day number

Add up the days in the months before, then add the date. For October 29, 2026: 273 days from January to September, plus 29 = day 302, leaving 63 days in the year. In a leap year every date from March 1 is one higher.

Frequently asked questions

What is a Julian date?

In manufacturing and the military it usually means the day of the year, often with the year in front: day 302 of 2026 is written 26302. That’s different from the Julian Day Number astronomers use.

What is today’s date in numbers?

It depends on where you are: month first in the U.S. (10/29/2026), day first in the UK and most of Europe (29/10/2026), and year first in the ISO standard (2026-10-29), which sorts correctly in spreadsheets and file names. The tool shows all three.
