ISO weeks are always whole, Monday to Sunday, so the numbering of 2022 starts on Monday, January 3, 2022, and ends on Sunday, January 1, 2023.
Other ways to count the weeks of 2022
Counted as whole blocks of seven days inside the calendar year, 2022 is 365 = 52 × 7 + 1, that is 52 weeks and 1 day. Both are true: the numbered ISO weeks are whole, so the first and the last of them may borrow days from the neighbouring years.
In the US numbering (weeks from Sunday, week 1 is the week that contains January 1) 2022 has 53 weeks, and week 1 starts on Sunday, December 26, 2021.
