Time zones are weird. I was doing some time zone research a couple of days ago, and I discovered that the first time zone to enter a new day is UTC+14, or the Line Islands. Wikipedia discusses a UTC-12 time zone for Howland Island, though Time and Date doesn’t mention this time zone, probably because none of the places in this time zone are inhabited. Doing some basic math tells me that in my time zone (at least during daylight saving time), a new day starts on the Line Islands at 6am my time the day before. This means I can wake up at 6am and seize two days at once!
Even without UTC-12, there are three days going on in the world at once for an hour every day. How wild is that? See if you can figure out when that is.
