Why people convert Tokyo to Copenhagen time
- Scheduling a call from Tokyo to Copenhagen: a 10:00 AM start in Tokyo lands at 3:00 AM in Copenhagen, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Tokyo and Copenhagen are inside the 9-to-5 working day between 4:00 PM and 5:00 PM JST time (9:00 AM–10:00 AM CEST). That is roughly 1 hours of usable overlap.
- Watching a live event or market open: Tokyo viewers need 2:00 AM in Copenhagen to catch a 9:00 AM start there, and 7:00 AM 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 -7h gap is not.
- Block 4:00 PM–5:00 PM JST as the recurring meeting window if you work primarily from Tokyo and need Copenhagen colleagues present.
- Copenhagen: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.
