When does the guarantee run?

Hello, Unfortunately, I can’t find an answer to my question quickly. Drive a procedure, which I picked up from the dealer 09/22. The car was therefore registered a few days before. According to the glue on the first page in the service booklet, the car was handed over to the importer at the end of 08/22. The glue basically says: guarantee start 31.08.22. the car was registered on 05.09.22. I picked it up on 07.09.22. The service info in the car itself is dated to 05.09.23. When do the 12 months start to run until the first inspection?
