Laura Dekker - International Date Line

The 180° line of longitude, exactly half way around the earth from Greenwich, UK
and 0° longitude is approximately where the International Date Line is located.






If you cross the IDL from the east to the west you gain a day (24hrs), as was the case for Laura and Guppy, who are now anchored at Vava'u in Tonga.
