Could somebody give me some insight on this. What is the 2568 letter? Or what does it look like? I’ve uploaded the letter from my gym from Office of Boxing Sport Board, Sports Authority of Thailand

Ministry of Tourism and Sports. I’m lost on what they are requesting. Thanks in advance

Does anybody know...

1). What is the Thai calendar year for year 1990?

2). There was a time back in the day when, if you obtained a Thai drivers license it was issued valid for life (no expiry date)... what was theThai calendar year that issued for life was no longer issued and they moved to an expiry date pls?

I would be most grateful for the answer, much appreciated.
