Questions
What is the best time for a meeting between US, UK and Singapore?
No working hour fits all three. The fairest is 6:30–7:30 am in US (Pacific), 2:30–3:30 pm in UK, 10:30–11:30 pm in Singapore. No hour fits everyone’s 9 am to 6 pm. At the closest fit, US starts 2½ hours early, and Singapore stays 5½ 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 6:30 am meeting move during the year?
Yes. Kept at 6:30 am in US (Pacific), it lands at 2:30 pm in UK and 10:30 pm in Singapore; then 1:30 pm in UK and 9:30 pm in Singapore; then 2:30 pm in UK and 9:30 pm in Singapore; then 1:30 pm in UK and 9:30 pm in Singapore over the year, as each place changes its clocks on its own date.
