我终於找到正确解答： 跟我之前说的一样，销售是星期一～日 点播是星期三到四。 在Billboard网站上看到的，所以一定正确。 http://www.billboard.com/bbcom/about_us/bbmethodology.jsp THE CHART WEEK Generally, charts reflect sales and airplay between Monday and Sunday of any given week. However, the mixed data charts (The Billboard Hot 100, Pop 100 and Hot R&B/Hip-Hop Songs) use an airplay cycle of Wednesday through Tuesday. Charts are available Thursday on Billboard.com and Billboard.biz and reflect the date of the Billboard issue in which they appear. In the case of online-only charts, it is the same issue date as all other charts reflecting data from the same seven-day period. The printed magazine first reaches newsstands on Friday. Each issue is dated based on the end of its publication week. Thus the Billboard that reaches newsstands on Friday, Sept. 9, for example, is dated Sept. 17. -- ◢█◣ wowowG ＠ 218-168-187-185.dynamic.hinet.net ◢█◣ 交 通 大 学 ˙ 机 械 工 程 学 系 ˙ 电 子 布 告 栏 系 统 ◥█◤ telnet://bbs.me.nctu.edu.tw ◥█◤
