Why people convert WET to Tokyo time
- Scheduling a call from WET to Tokyo: a 10:00 AM start in WET lands at 7:00 PM in Tokyo, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +9h gap: WET and Tokyo 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 Tokyo is 6:00 PM in WET.
- Watching a live event or market open: WET viewers need 6:00 PM in Tokyo to catch a 9:00 AM start there, and 3:00 PM if the event is anchored to WET.
- Always state the zone abbreviation, not just the hour. "3:00 PM WET" is unambiguous; "3 PM" across a +9h gap is not.
- With a +9h gap there is no shared 9-to-5 window, so alternate the early start: one week WET takes the early slot, the next week Tokyo does.
