What week 1 of 2029 means
ISO 8601 numbers weeks so every week starts on Monday and ends on Sunday. Week 1 is the one holding the year's first Thursday, which is why early January can land in week 52 or 53 of the previous year. Week 1 is one piece of that system.
In 2029, week 1 covers Jan 1 – Jan 7, 2029. That's January, deep in Q1. The same week number shifts by a day or two each year, so week 1 in 2030 won't share these exact dates. The table below shows how it moves.
Want to check a specific date instead of a week number? The week calculator converts any date to its ISO week. Curious how many weeks a year holds? The weeks in a year guide explains 52 versus 53. And the ISO week number page covers the standard end to end.
