Why people convert Thailand to China time
- Scheduling a call from Thailand to China: a 10:00 AM start in Thailand lands at 11:00 AM in China, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Thailand and China are inside the 9-to-5 working day between 9:00 AM and 4:00 PM ICT time (10:00 AM–5:00 PM CST). That is roughly 7 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Thailand is 9:00 PM in China makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a +1h gap is not.
- Block 9:00 AM–4:00 PM ICT as the recurring meeting window if you work primarily from Thailand and need China colleagues present.
