How to Say “Have a good day” in Thai
ขอให้มีวันที่ดี
khɔ̌ɔ-hây mii wan thîi dii
Have a good day
literally: I wish that you have a day that is good
ค่ะ (khâ) and ครับ (khráp) are polite particles — they depend on the speaker's gender, not the listener's.
Word by word
When to use it
In Thai culture, we don't traditionally say "Have a good day!" to each other. This Thai version came about through cultural mixing — foreigners wanting to say the phrase to Thai people. If a foreigner says it, Thai people won't find it strange at all, but between two Thai people it sounds a little odd. ขอให้ (khɔ̌ɔ-hây) is the reusable piece: ขอให้ (khɔ̌ɔ-hây) + [subject] + [good outcome] means "may [subject] have or be [good outcome]" — the same pattern behind ขอให้หายเร็วๆ (khɔ̌ɔ-hây hǎay rew-rew) — Get well soon; and ขอให้สนุก (khɔ̌ɔ-hây sa-nùk) — Have fun.
Why you've seen it spelled differently
You may have seen ขอให้มีวันที่ดี written as: kor hai mee wan tee dee, kho hai mi wan thi di, khor hai mee wan tee dee.
There is no single standard for writing Thai in the Roman alphabet — phrasebooks, road signs, and tourist guides each follow a different system, and many just invent their own spellings. The romanization on this page uses a consistent IPA-based system that marks all five tones and distinguishes short from long vowels. The same word always gets the same spelling.
