Word by word
When to use it
Used for both the Western New Year (January 1st) and the traditional Thai New Year, Songkran, in April. While สวัสดีปีใหม่ (sa-wàt-dii pii mày) perfectly covers both occasions, during Songkran you'll also hear more specific festive variations such as สวัสดีปีใหม่ไทย (sa-wàt-dii pii mày thay) — Happy Thai New Year; สวัสดีวันสงกรานต์ (sa-wàt-dii wan sǒng-kraan) — Happy Songkran Day; and สุขสันต์วันสงกรานต์ (sùk-sǎn wan sǒng-kraan) — also Happy Songkran Day.
Why you've seen it spelled differently
You may have seen สวัสดีปีใหม่ written as: sawatdee pi mai, sawadee pee mai, sawatdii bpii mai.
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.
