Most readers will have heard of the International Date Line, established as an irregular line, drawn by convention through the Pacific Ocean, substantially along the 180th meridian IDL marks the place where the date changes.
Crossing the line from west to east, travelers gain a day and, conversely, lose a day traveling east to west.
The position of the IDL has been arbitrarily designated and is partly curved to accommodate eastern Siberia, then bulges westward again in order to avoid crossing land.
Let us now assume that a successor of the Concorde can take its passengers around the equator, cicrcling the globe in six hours. Flying west to east it will cross the IDL four times in 24hours and consequently lose four days. Starting, say, in the 18th of March it will land on the 14th of March. Continuing the journey the passengers will go back into history eventually reliving the birth of Christ. Is there something wrong with this reasoning???

Well lets go one farther than that as you revolve around the world you would also cross time zones and as you crossed each one you would gain another hour so depending on the number of time zones you could maybe gain yet another day this way , so every time that you crossed the date line you could probably gain two days instead of just one, well what do you think so far?? Now here goes , the international date line is an imaginary line , and just by crossing it it will not change time , and besides that even if it were possible sooner or later you would need to refuel and even as recent as 100 years ago I doubt that there were many places to get a good grade of aviation fuel so I see a lot of holes in your theory

Yes there is a lot wrong with that reasoning...
I am very sorry to report that the successor to the Concorde takes from 4 to 5 hours to clean up, refuel, replenish all consumeables, and get tested for subsequent flights. So, given the outrageous fuel consumption of this aircraft, many frequent gas stops will be needed and each one is quite lengthy. Time possibly gained by flying against the path of the Sun over the Earth is therefore lost in maintenance, crew changes, and resupply functions.
Consider if you will that the path West to East in a straight line (aircraft do not fly in straight lines) around the Earth (to gain a day) is at least 25,000 miles... Nope. Not in one flight. Not today.
Oh, you want to do this four times? Figure on 16 layovers at least with each stop lasting a minimum of 4 hours.
I would not plan on going back, or ahead in time at any time in our lifetime. Just because we call it yesterday or tomorrow for the sake of convenience to the inhabitants who live on a particular spot on the Earth, instantaneous time is the same everywhere.

You don't actually lose or gain a day. It's just that when you arive in your destination their clocks are set to a different time. However time travel into the future is possible in a way. If you travel into space you age slower than normal so if you were traveling at near the speed of light you could go out into space and when you came back the Earth and everyone on it would of aged something like 4 times more than you. Going into the past requires alot more imaginative thinking involving piloting ships close to the edge of black holes.

If you're going to change your calendar and clock each time your cross the IDL, you have to do it in EVERY time zone you cross. The day you "gain" at the IDL will be whittled away as you reset the clock 24 times as you pass through the time zones around the world.
Nice try. But you can't have your cake and eat it, too.

i say it is now two days ago. and the date has now been pushed back two days. this is basicly the reasoning your using. i have not CHANGED the actual time flow. i have not MOVED through time. i have simply SAID the date is two days back. this is same reasoning.
time zones are the same convention. we SAY if you move across the earth such and such amount then we move the clock by such and such amount. time has not changed. we are just correlating the possition of our clock with the relative possition of the sun in the sky. traveling around the globe does not make you go back in time (traveling at speed will SLOW time in a relativistic sense but this is neither here nor there. unless your going a significant percentage of the speed of light you will never notice this effect)

Yes. I believe here on earth some have traveled.Take the earths speed rotation+ Earths orbit around the Sun + Solar System speed in the Galaxy + Galaxy speed add all, and figure what longitude,and latitude on what given day,plus speed of a craft you need to be in. Could it be,you are moving faster than light.

Hmmm - you will also cross local 'midnight' five times in the course of your travels, and will unfortunatley land on the 19th of March. You may however, make it time for the rebirth of Christ.

Time in that respect is a man made thing and not actual.
You will never grow younger or regress by flying round the world

in a matter of technicalities i would say you are correct. but a physical reversal of the decay that time measures is a bit unreasonable. if someone was born on february 29th in 2000, by the year 2020 will they only have had five birthdays? thechnically yes, but they will not be five years old, they will be twenty.
in all actuality you would just be skipping back and forth between today and yesterday four times.

the international date line is just a point where we SAY the new day begins it could just as easily be when the sun rises where you are
time travel is possible - all things are possible
but it is about as probable to go back in time as a sneeze cracking the earth in two ( we travel FORWARD in time all the time lol )
