My year is showing as 2565 BE. How can I change it to 2022

Your iPhone's calendar format is set at Buddhist. Go to Settings -> General -> Language & Region > Calendar and change to Gregorian.

The support article you came here from should provide you with the steps needed to try to resolve this issue. Have you tried them all yet? If so, and they didn't help, I suggest that you contact Apple Support directly. To do so, simply select the "Get Support" link in the upper right-hand side of this forum's web page

Good catch! I totally missed that one. Thanks!

It's one of the more obscure settings I would agree 😃
