Oricon

, also known as Oricon Style, is a Japanese company which provides music industry-related information. It is best known for the music charts it produces, similar to those published by Billboard Magazine in the USA. The name "Oricon" is derived from the English words "Original Confidence". The "Oricon Year" runs (as of 2006) from mid-December of one year to mid-December of the following year (was previously the beginning of December of one year, to the end of November the following year). Also to note, Oricon combines the last week of December with the first week of January, therefore an "Oricon Year" has 51 weeks versus a real year, which has 52 weeks. Despite this these weeks are counted as 2 instead of 1 in the chart run of a single or an album.
