Why people convert JST to Lima time
- Scheduling a call from JST to Lima: a 10:00 AM start in JST lands at 8:00 PM in Lima the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -14h gap: JST and Lima 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 Lima is 7:00 PM in JST.
- Watching a live event or market open: JST viewers need 7:00 PM in Lima to catch a 9:00 AM start there, and 2:00 PM if the event is anchored to JST.
- Always state the zone abbreviation, not just the hour. "3:00 PM JST" is unambiguous; "3 PM" across a -14h gap is not.
- With a -14h gap there is no shared 9-to-5 window, so alternate the early start: one week JST takes the early slot, the next week Lima does.
