I tried it on a couple of accounts, it really shows the exact date.

Answer 1

For example, this site does not work for me, it shows an error, perhaps because I changed the name of my Instagram account. I once read that Instagram was originally created without viewing the date of registration, so it is possible that they will continue to adhere to this policy.

Answer 2

He just stupidly takes the date of the first photo.

Answer 3

Approximate date
He looks at what dates are on the photos on the accounts before and after you, all accounts have consecutive IDs
