- Scheduling a call from ART to BRT: a 10:00 AM start in ART lands at 10:00 AM in BRT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both ART and BRT are inside the 9-to-5 working day between 9:00 AM and 5:00 PM ART time (9:00 AM–5:00 PM BRT). That is roughly 8 hours of usable overlap.
- Watching a live event or market open: ART viewers need 9:00 AM in BRT to catch a 9:00 AM start there, and 12:00 AM if the event is anchored to ART.
