Week numbers 2028
2028 has 52 ISO weeks. Week 1 starts Monday 3 January 2028; week 52 ends Sunday 31 December 2028.
ISO 8601 week numbering: weeks run Monday–Sunday, and a week belongs to the year that contains its Thursday — so the first days of January can belong to the last week of the previous year, and vice versa.
