Times of the Day 
Dtɔɔn means section or period of time. It occurs commonly with the words for morning, afternoon, evening etc. Note that when referring to the time when an action takes place, Thai does not need the word for “in”
dtɔɔn-cháao morning, in the morning
dtɔɔn-tîang midday, in the midday
dtɔɔn-bàai afternoon, in the afternoon
dtɔɔn-yen evening, in the evening
dtɔɔn glaang-wan daytime, in the daytime
dtɔɔn glaang kuun night time, at night
Time expressions can occur at the beginning or end of a sentence, as in English:
1.dtccn-yen pǒm ja bpai kâang -nɔɔk.ตอนเย็นผมจะไปข้างนอก. In the evening I will go out.
2.Pǒm duum gaafɛɛ dtɔɔn-cháao.ผมดื่มกาแฟตอนเช้า.I drink coffee in the morning.
3.káo chɔɔp rian paa-sǎa Thai dtɔɔn bàai.เขาชอบเรียนภาษาไทยตอนบ่าย. She likes to learn Thai in the afternoon.
