DATE LINE LOSE A DAY
Planet Earth is divided into 24 different time zones and regardless of where you are on the planet, the time and date always changes at midnight. So, for those who travel westwards, time moves seemingly “slower” over the time zones gaining one hour per time zone crossed, but you suddenly find yourself one day older when crossing the date line from the Western to the Eastern Hemisphere since you have to adjust for the time “gained”! Just to confuse matters even further, the IDL (International Date Line) is arbitrary, and countries can request to move it as they please!
For two hours of every day (between 10 am and 12 pm GMT), the world has three different dates, meaning that when it is 11.30 pm on Sunday in American Samoa (GMT-11), it will be 6.30 am on Monday in New York City (GMT-4) and 12.30 am on Tuesday in Kiritimati, Line Islands (GMT+14)!
