Questions
What is the best time for a meeting between US, UK and Australia?
No working hour fits all three. The fairest is 3:30–4:30 pm in US (Eastern), 8:30–9:30 pm in UK, 7–8 am, next day in Australia (Adelaide). No hour fits everyone’s 9 am to 6 pm. At the closest fit, UK stays 3½ hours late, and Australia starts 2 hours early.
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 3:30 pm meeting move during the year?
Yes. Kept at 3:30 pm in US (Eastern), it lands at 8:30 pm in UK and 7 am next day in Australia; then 7:30 pm in UK and 6 am next day in Australia; then 8:30 pm in UK and 6 am next day in Australia; then 8:30 pm in UK and 5 am next day in Australia; then 8:30 pm in UK and 6 am next day in Australia; then 7:30 pm in UK and 6 am next day in Australia over the year, as each place changes its clocks on its own date.
