What week 52 of 2028 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 52 is one piece of that system.
In 2028, week 52 covers Dec 25 – Dec 31, 2028. That's December, deep in Q4. The same week number shifts by a day or two each year, so week 52 in 2029 won't share these exact dates. The table below shows how it moves.
