You "gain" a day because when you cross the IDL in the easterly direction, you
take the last page that you tore off of your calendar, and glue it back on, thus
gaining the ability to live the past 24 hours again.
The International Date Line is where you either gain or lose a day when you cross it, depending on the direction of travel.
When you cross the International Date Line traveling from Asia to North America, you will lose a day. This is because the Date Line serves as the boundary for calendar days; when you cross it from east to west, you subtract a day. For example, if it's Monday in Asia, upon crossing the Date Line, it will be Sunday in North America.
When you cross the International Date Line, you move from one day to the next. This imaginary line on the Earth's surface marks the change in calendar days.
