Asking for the Time
To ask what time it is, Thai uses the question word กี่โมง. You can combine this with a time word like ตอนนี้ (now) to ask for the current time. Place the question word at the end of the phrase, before any polite particles.
Daytime Hours
To state the time during the day, use a number followed by the hour marker โมง. If the time is exactly on the hour, you can emphasize this by adding ตรง (exactly) at the very end.
To ask what time an action or event begins, state the action followed by กี่โมง. If the time is half-past the hour, add ครึ่ง (half) after the hour marker.
Noon and Afternoon
For 12:00 PM (noon), Thai has a specific word: เที่ยง. You do not need to add a number or an hour marker to it.
For the afternoon (1 PM to 3 PM), the word บ่าย is placed before the number and hour marker. For example, 2 PM is บ่าย สอง โมง.
Evening Hours
Thai uses a different system for the evening (7 PM to 11 PM). Instead of the daytime marker, you use the evening hour marker ทุ่ม. Counting restarts at 7 PM. This means 7 PM is "one" evening hour (หนึ่ง ทุ่ม), 8 PM is "two" evening hours (สอง ทุ่ม), and so on up to 11 PM (ห้า ทุ่ม).
When asking or stating what time a scheduled event like school or work finishes, use the verb เลิก.
