Understanding the +10h Gap: São Paulo vs Thailand

Why people convert São Paulo to Thailand time

Scheduling a call from São Paulo to Thailand: a 10:00 AM start in São Paulo lands at 8:00 PM in Thailand, so you can confirm the slot without doing the arithmetic yourself.
Handling a +10h gap: São Paulo and Thailand have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Thailand is 7:00 PM in São Paulo.
Keeping family and friends in sync: knowing that 8:00 PM in São Paulo is 6:00 AM in Thailand makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM BRT" is unambiguous; "3 PM" across a +10h gap is not.
With a +10h gap there is no shared 9-to-5 window, so alternate the early start: one week São Paulo takes the early slot, the next week Thailand does.

About BRT (Brasilia Time)

About ICT (Indochina Time)

Indochina Time (ICT) is used across Southeast Asia including Vietnam, Thailand, Laos, and Cambodia. Indonesia (Western time, WIB) also uses UTC+07:00. ICT does not observe daylight saving time.

Best time to call between São Paulo and Thailand

With a +10h offset there is no overlap inside a normal 9 AM – 5 PM day. Thailand opens at 9:00 AM ICT, which is 7:00 PM in São Paulo, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

São Paulo and Thailand have no shared working hours because of the +10h gap. Teams need to alternate early starts or rely on asynchronous handovers.

São Paulo is 10 hours ahead of Thailand (BRT UTC-03:00 → ICT UTC+07:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
