How To Congratulate My Friend With Birthday Of His Majesty The King In Thai?

[sb1983]

Is there any tradition or commonly used phrases that Thai people use to congratulate each other with the birthday of His Majesty The King? I would like to say something good and polite for my Thai friend.

There isn't really a tradition where you'd congratulate or mention anything regarding the King's birthday.

In fact, conversation topics regarding royalty are kind of taboo here in Thailand and is not really appropriate in casual conversations or greetings.

สวัสดี วัน พ่อ

sawatdee wan por is the informal greeting I hear.

I agree with the observation above.
