Frequently asked questions
What month is week 50 in?
Week 50 typically falls in December. 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 50 as a week code?
The ISO code is the year plus W50 — for example 2026-W50, short form 26W50, or YYWW date code 2650. 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.
