Frequently asked questions about week numbers
Which week of the year is it now?
The live counter above shows today's week number. It follows ISO 8601: weeks start on Monday and week 1 is the week that contains the first Thursday of the year.
How many weeks are in a year?
An ISO year has 52 or 53 weeks. It has 53 weeks when 1 January is a Thursday (or a Wednesday in a leap year). 2026 has 53 weeks.
Why is 1 January sometimes in the last week of the previous year?
Under ISO rules, week 1 contains the first Thursday. If 1 January is a Friday, Saturday or Sunday it belongs to week 52 or 53 of the previous year, and some days at the end of December can belong to week 1 of the next year.
What is the week number used for?
