Why people convert Tokyo to Colombia time

  • Scheduling a call from Tokyo to Colombia: a 10:00 AM start in Tokyo lands at 8:00 PM in Colombia the previous day, so you can confirm the slot without doing the arithmetic yourself.
  • Handling a -14h gap: Tokyo and Colombia 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 Colombia is 7:00 PM in Tokyo.
  • Watching a live event or market open: Tokyo viewers need 7:00 PM in Colombia to catch a 9:00 AM start there, and 2:00 PM if the event is anchored to Tokyo.
  • 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 Tokyo takes the early slot, the next week Colombia does.
