What is meant by ‘six-day week’ and ‘eight-day week’?

1.	What is meant by ‘six-day week’ and ‘eight-day week’?
Answer» When crossing eastward towards America (from Japan to U.S.A.) a day must be subtracted. When crossing the date line ships gain a day from the calendar and have an ‘eight- day week’. It repeats a day. If ship crosses the date line on Monday, the next day will be again Monday and not Tuesday.
