Can you show how you are getting that result? In a specific component, script, etc.?

Thx. You are right that addDays(now(),-8)) returns the correct date. I thought that was the problem.

But no, dateFormat(addDays(now(),-8),‘YYYY-MM-dd’) returns 2022-12-27. Am I using dateFormat correctly?

No, you’re not 🙂  
`YYYY` is week year, not calendar year (`yyyy`):
