To quote bluegie:
Quote:
OK... lemme explain.
GUILTY (released on 01.01)
Dec 25 was the last Wednesday of December, and oricon does not update the weekly chart at all after the last Wednesday of December.
Kanjani8 (released on Dec 23rd - 25th)
This year the last Wednesday is NOT Dec 23rd. It's Dec 30th. That means Oricon will still update the weekly chart between 12.22 - 12.28.
The double week does not depend Dec 25th or Dec 26th or x'mas etc. It depends on when the last Wednesday is before new year. It can be any date between 25th to the 30th of December.
Another thing that indicates whether the cds fall into the double week: the release date is set on Jan 01. Kanjani8 will fall into such category if the release dates for the triple singles are: Jan 01, 02, and 03.
