Best time to schedule a meeting
Standard 9–5 working hours do not overlap at all between MMT and BRT. Someone has to take an early or late call — or use asynchronous communication instead.

About MMT
Myanmar Time (MMT) is UTC+6:30. It is used in Myanmar, all year.
Myanmar Time is UTC+6:30, another of the half-hour zones and one of only a handful in Asia. It has no daylight saving. The same offset is used by the Cocos Islands, which is the only other place on it, so a UTC+6:30 timestamp is almost always Myanmar.
About BRT
Brasília Time (BRT) is UTC−3. It is used in São Paulo, Rio de Janeiro and most of populated Brazil.
Brasília Time is UTC−3, covering São Paulo, Rio de Janeiro and Brasília. Brazil abolished daylight saving in 2019, so the offset is now fixed year-round — but a great deal of older software, and a lot of published advice, still assumes the southern-hemisphere shift that used to run from October to February. If a Brazilian meeting time was correct last year and is an hour out now, an out-of-date time zone database is the likely cause.
Does this gap change with the seasons?
Neither MMT nor BRT shifts with the seasons, so this 9.5-hour difference holds all year. That is unusual enough to be worth relying on: most cross-continental gaps move twice a year.
This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
Frequently asked questions
What time is 9:00 AM MMT in BRT?
9:00 AM MMT is 11:30 PM BRT (previous day).
Is BRT ahead of MMT?
BRT is 9 hours 30 minutes behind MMT.
Which time zone does this use?
MMT is UTC+6:30 and BRT is UTC−3. Both abbreviations denote a single fixed offset, so this conversion never shifts with daylight saving — what changes is which abbreviation a place is using at the time.
