Frequently asked questions
What week number is it today?
The number at the top of this page is the current ISO week, based on the date on your device.
How are week numbers calculated?
This page uses ISO 8601, the standard across Europe and much of Asia. Weeks start on Monday, and week 1 is the week that contains the first Thursday of the year, which is also the week containing 4 January.
Why do some years have 53 weeks?
A year has 52 weeks and one or two days left over, so every five or six years the leftover days add up to an extra ISO week. It happens when a year starts on a Thursday, or a leap year starts on a Wednesday.
Can 1 January be in week 52 or 53?
Yes. If 1 January falls on a Friday, Saturday or Sunday, it belongs to the last week of the previous year in the ISO system.
How do I plan what happens each week?
