The International Date Line largely coincides with the 180th de-
gree of longitude on the surface of the earth. Yesterday's date
applies if this line is crossed in an easterly direction, and you
move into the next day if it is crossed in a westerly direction. The
same date applies throughout the entire world only once a day,
namely at midnight on the International Date Line.
