ISO weeks are always whole, Monday to Sunday, so the numbering of 2030 starts on Monday, December 31, 2029, and ends on Sunday, December 29, 2030. To see these weeks inside the months, open the 2030 calendar with week numbers.
Why 2030 has 52 ISO weeks
2030 starts on Tuesday, January 1, 2030, and ends on Tuesday, December 31, 2030; it is a common year of 365 days. Neither condition holds, so it has 52 numbered weeks. Week 1 is the week that contains the first Thursday of the year, January 3, 2030.
Counted as whole blocks of seven days inside the calendar year, 2030 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) 2030 has 52 weeks, and week 1 starts on Sunday, December 30, 2029.
