The next thing si the timing of book closing.

In business, most companies in Japan close their books at the end of month and at the end of March for year-end closing. For your private book, however, you can set closing timing whenever you like. For example, your pay day is every 15th. You might want to know how much you go around for saving. You can start your book from 16th to next 15th as you want.
