The International Date Line (IDL) is the demarcation where one calendar day changes to the next. When you cross the IDL from east (e.g., from America) to west (e.g., towards Asia), you are moving into an area where the time of day is similar, but the calendar date is one day ahead. Therefore, you must add one day to your calendar. Conversely, crossing from west to east requires subtracting a day.
