What week 9 of 2023 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 9 is one piece of that system.
In 2023, week 9 covers Feb 27 – Mar 5, 2023. That's February / March, deep in Q1. The same week number shifts by a day or two each year, so week 9 in 2024 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.
