Gets the number of weeks that are included in Java for 2 time periods (week of stock, from Saturday to Friday)

The Calendar class was started on the first day of Sunday, so Calendar.day_of_week is 1 when it was Sunday.

In the stock there is a day K week K and the month K data.

The week k in this refers to the data for the week of the trading day, which is a cycle from Saturday to Friday.
