June in Thai is มิถุนายน pronounced mí-tù-naa-yon. Like all months (เดือน deuan) in Thai that have 30 days, it ends with ยน (yon).

The abbreviated version of มิถุนายน is มิ.ย.

The beginning of มิถุนายน is มิถุน (mí-tŭn) which comes from the Gemini Zodiac sign. The reason for this is that months in Thai all come from zodiac signs

The new Queen’s Birthday

Queen in Thai is (พระราชินี prá raa-chí-nee). Birthday is (วันเกิด wan gèrt). So the queens birthday is วันเกิดของพระราชินี (wan gèrt kŏng prá raa-chí-nee).

The birthday of the new queen named Suthida Bajrasudhabimalalakshana falls on June 3. This became a national Holiday in 2019.
