In the local time of each, during what times of the 24-hour day in January, and in July, is it the same day of the week in Canberra and in Honolulu? Canberra goes on daylight savings time in summer but Honolulu does not. Standard time in Canberra is GMT plus 10 hours, whereas Honolulu time is GMT minus 10 hours.

What would the answer be if somehow (by magic, perhaps) Australia and Hawaii were to be moved so that standard time in Canberra was GMT plus 12 hours and time in Honolulu was GMT minus 12 hours?

How would the answers to the questions above be affected if the International Date Line were moved to the prime meridian instead of being (roughly) directly opposite as it now is?

(In reply to re(3): first and second part (Spoiler) with ? on 3rd by Richard)

The Mike and Yankee time zones are actually the same time zone, but for different days, hence, they are also known as IDLE and IDLW, respectively.  By moving the IDL to the prime meridian, the Zulu time zone would become divided into two zones.
