Frequently asked questions
What month is week 33 in?
Week 33 typically falls in August. The exact dates shift by up to a few days from year to year because week 1 is anchored to January 4, not January 1.
How do I write week 33 as a week code?
The ISO code is the year plus W33 — for example 2026-W33, short form 26W33, or YYWW date code 2633. See week number formats.
Are these dates the same in every country?
Yes for ISO 8601 (Monday-start) numbering, which is what this table shows. US Sunday-start calendars can label the same days with a number one higher — see week start conventions.
