Why people convert Bangkok to Doha time
- Scheduling a call from Bangkok to Doha: a 10:00 AM start in Bangkok lands at 6:00 AM in Doha, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Bangkok and Doha are inside the 9-to-5 working day between 1:00 PM and 5:00 PM ICT time (9:00 AM–1:00 PM AST). That is roughly 4 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Bangkok is 4:00 PM in Doha 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 -4h gap is not.
- Block 1:00 PM–5:00 PM ICT as the recurring meeting window if you work primarily from Bangkok and need Doha colleagues present.

About AST (Arabia Standard Time)
Arabia Standard Time (AST) is fixed at UTC+03:00 all year across Saudi Arabia, Qatar, Kuwait, Bahrain, Iraq and Yemen.

Arabia Standard Time is the same offset as Moscow Standard Time and East Africa Time, which makes scheduling with Europe straightforward — Riyadh is one hour ahead of Central European Time in winter and level with it during European summer time.
