Why people convert Tokyo to BST time
- Scheduling a call from Tokyo to BST: a 10:00 AM start in Tokyo lands at 2:00 AM in BST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -8h gap: Tokyo and BST 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 BST is 1:00 AM in Tokyo.
- Keeping family and friends in sync: knowing that 8:00 PM in Tokyo is 12:00 PM in BST makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM JST" is unambiguous; "3 PM" across a -8h gap is not.
- With a -8h gap there is no shared 9-to-5 window, so alternate the early start: one week Tokyo takes the early slot, the next week BST does.

During BST, London is one hour ahead of UTC, four hours ahead of New York on Eastern Daylight Time, and five hours ahead of New York once the United States returns to Eastern Standard Time in November.
