Scheduling across regions
Remote hiring and vendor calls multiply timezone friction. Comparing zones upfront surfaces the narrow band where everyone is awake and nominally within business hours.
DST trap doors
India stays at UTC+5:30 year-round; US zones spring forward and fall back. Calendar apps usually handle offsets—still verify the week of the meeting manually for external clients.
Core hours policy
Document team “core hours” in one reference zone, then map outliers. Async updates fill gaps; live workshops should land inside the shared overlap you identify here.
Customer support windows
SLA clocks often anchor to business hours in a hub city. Compare zones when promising “same-day response” to international accounts.
