What week 41 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 41 is one piece of that system.
In 2023, week 41 covers Oct 9 – Oct 15, 2023. That's October, deep in Q4. The same week number shifts by a day or two each year, so week 41 in 2024 won't share these exact dates. The table below shows how it moves.
