s3 - date folder structure for etl data processes (airflow, etc)

Trying to verify the best practice. Say I have a "folder" structure like so:

s3://my-bucket/events/2022/09/01
s3://my-bucket/events/2022/09/02
...

As an example, On 9/3, the client should export into the "folder" s3://my-bucket/events/2022/09/02 (after the 9/2 day).

We have a client who is running their etl on 9/3 and then placing the files on 2022/09/03 folder and we're trying to convince them to put it in the 9/2 folder.

Am I correct is saying that this is the best practice?
