Understanding week numbers in 2035

ISO 8601 gives every week a number from 1 to 52. Each week runs Monday to Sunday, and week 1 is the one holding the year's first Thursday. So if January starts late in the week, those early January days belong to the last week of 2034.

2035 runs the standard 52 weeks. Years only get a 53rd week when January 1 falls on a Thursday (or a leap year starting Wednesday), which is why most years stop at 52.

Want a single week instead of the full year? Each row links to its own detail page. Need to convert a date? The week calculator handles that. And the weeks in a year guide explains 52 versus 53 in depth.
