The earth is rotating. You start counting days.
If you travel in same direction (looks like you move in opposite to the sun's path) you get shorter days. The sun sets sooner for you as you are. "running away from the day".
You hardly notice this difference but you are resetting your watch every day when traveling.
After 81 days of traveling you have 'run out' on the sun by a day. So although you seem to have travelled 81 days, you were only gone 80.
Makes sense? I hope so.

it is because he did not time how long it took.
If he had a stop watch it would have measured 80 days by the time he arrived home.
But he timed it by counting the number of times the sun rose and set.
Imagin that you could run around the world in 1 hour. you would be moving so fast that you would watch the sun rise and set and rise again. Thus you would think that it took you one day according to the sun, but according to your watch it only took one hour.
I hope that makes it a bit more clear

the concept was actually he thought he was right on time .. and he took 80 days .. but actually he had taken 79 days .. and saved a day coz when u travel aroud the world.. u have changed 24 time zones .. and hence ur clock is now 24 hours behind .. i dont think i will be able to explain it right .. but it goes something on those lines nd that show they saved a day .. they were goin from the west to the east...

If I remember correctly, this is how it works. When you travel east, you gain time as you cross each date line, so that once you've completed the circumference of the globe, you've gained 24 hours, hence the one day. If you watch the "around the world in eighty days" version with Pierce Brosnan in it, he actually explains it at the end of the movie. Hope this helped.

according to the greenwhich mean time, there's a time gap in all nations, so jackie adjusted his watch according to the local time. this way, when they reached the original place, they thought they had taken 81 days, but actually it was 24 hrs ahead, so he took only 80 days

When you travel from the west to the east across the International Date line you have to reduce a day . Seems crazy but that's a fact.

If you travel from west to east i.e. from England to Asia then you have to keep advancing your watch as you move east. when you reach the international date line the time is the same only it is 1 day earlier.
If you cross the dateline from east to west you are losing one day.
