Questions
What is the best time for a meeting between US, UK and Japan?
No working hour fits all three. The fairest is 7–8 am in US (Central), 1–2 pm in UK, 10–11 pm in Japan. No hour fits everyone’s 9 am to 6 pm. At the closest fit, US starts 2 hours early, and Japan stays 5 hours late.
Is there an hour when all three are awake?
No. There’s no hour when everyone is between 8 am and 10 pm, so someone always takes the call early or late.
Does a weekly 7 am meeting move during the year?
Yes. Kept at 7 am in US (Central), it lands at 1 pm in UK and 10 pm in Japan; then 12 pm in UK and 9 pm in Japan; then 1 pm in UK and 9 pm in Japan; then 12 pm in UK and 9 pm in Japan over the year, as each place changes its clocks on its own date.
