What are the best hours to schedule a call between BRT and KST?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. Brasilia and Korea are 12 hours apart, which is too far for an overlap, so somebody has to take a call outside their own working day. The least painful options are below, ranked by how close both sides sit to the middle of the afternoon.
| BRT | KST | Working hours | Note |
|---|---|---|---|
| 7:00 am | 7:00 pm | neither side | early morning in Brasilia, evening in Korea |
| 7:00 pm | 7:00 am the next day | neither side | evening in Brasilia, early morning in Korea |
Does daylight saving change BRT to KST?
Brasilia Time does not move its clocks at all, so its UTC-3 offset holds every day of the year.
Korea Standard Time does not move its clocks at all, so its UTC+9 offset holds every day of the year.
Is BRT ahead of or behind KST?
BRT is behind KST by 12 hours: when it is 12:00 pm in Brasilia, it is 12:00 am the next day in Korea. Neither Brasilia Time nor Korea Standard Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
Brasilia Time covers Sao Paulo and Rio de Janeiro, fixed since Brazil dropped summer time in 2019. Korea Standard Time covers Seoul and South Korea. The identifiers behind them are America/Sao_Paulo and Asia/Seoul, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
