Change from 12/30/2017 to 1/06/2018

I was looking through the 2017 and 2018 charts and I noticed that there may be an extra chart somewhere between December 30th, 2017 and January 6, 2018.

The #1 song both charts, “Perfect” by Ed Sheeran, showed as “2 weeks at #1” the first week, and “4 weeks at #1” the second week. Looking at other songs in the Top 40 I noticed the total weeks on chart increases by 2 and the “Last Week” position is different. I saw that on the page and on Billboard’s page for those weeks.
Billboard’s 200 chart also had a similar behavior. Is there a date for that “middle” chart or is it just an extra chart for one of those weeks?

Hi Glen,

How are you? I am one of the administrators here and I’ll try to answer your question to the best of my ability.

Prior to 2018, Billboard’s Hot 100 information was collected on a Saturday, tabulated on a Tuesday and posted on a Thursday which was nine days before the week ending print date. So using current dates as an example, Billboard would collect data for the issue week ending July 11, 2020 based on on the data (sales/airplay/streaming/et al) collected between Sunday, June 21, 2020 to Saturday, June 27, 2020. On Tuesday, June 29, 2020, all of that data would be tabulated to create the Hot 100. The results would be released to record labels and music insiders on Thursday, July 2, 2020. That weekend, it would be published and printed in Billboard to be shipped and received in stores for Monday, July 6 for the week ending July 11, 2020. Are you still with me?

Since data can be acquired faster, Billboard now saves almost a week between data gathering and publication. So now, data collected between Sunday, June 28 to Saturday, July 4 will be tabulated on Sunday, July 5, given to insiders on Monday, July 6, and published online Tuesday, July 7 for week ending July 11. Are you dizzy? Still here?

Why did I go through all of that? To confirm with you that you are correct about that missing week. By deciding to modify their lag between data collection and publication, they chose the softest week of the year to make that switch. So what they did was create a chart that was unpublished to get them up to speed. That “missing week” is January 3, 2018…and I have it! I’ll ask one of our techies to post it for continuity purposes. I’ll also attach the article that explains what I said but in a much more convoluted way.

Thanks for the question.


I was slightly confused, but I get it. Thanks!

You might want to transcribe the Billboard article because I could only read the first two paragraphs (as I am not a “pro”).

Hey Jarrett, I was wondering if you could send me your copy of that missing chart for my records. Unless it is already in my stash pile of your charts already sent and I missed it previously. Thank you.

On its way… :smile:

I’m not a “pro” either but I’ll see what I can do…

Watch this space. :smile:

Well, whaddaya know…


Billboard Chart & Magazine Dates Now to Align Closer to Release Week


Chart and issue dates will now be dated to the Saturday after charts post online and the magazine is published.

Beginning with the first charts and magazine issue of 2018, Billboard announces a shift in the way that both will be dated.

As of the first magazine published in 2018, issues and all charts within will be dated to the Saturday of the week that that the magazine is shipped. Currently, Billboard issues are dated to the Saturday in the week following shipment.

For, the adjustment will result in charts being dated to the Saturday following their posting, or four days after the Tuesday refresh of all rankings on the website. Currently, charts are dated 11 days after first posting online (or, to the second Saturday after charts post).

The first Billboard issue of 2018 will be dated Saturday, Jan. 6; since Monday, Jan. 1, is a holiday, its corresponding charts will post online a day later than usual, on that Wednesday, Jan. 3. From there, in all non-holiday weeks, charts will post each Tuesday and be dated to the Saturday four days later.

As an example, the issue dated Jan. 27 will arrive four days after its corresponding charts (also dated Jan. 27) post online Jan. 23. (That issue will arrive on newsstands Friday, Jan. 26.)

As for data tracking weeks for Billboard 's charts, the Billboard Hot 100, for example, dated Jan. 27 will cover streaming and sales data from Friday, Jan. 12, through Thursday, Jan. 18, and radio airplay data from Monday, Jan. 15 through Sunday, Jan. 21 (as airplay follows a different tracking week than sales and streaming). The Billboard 200 albums chart dated Jan. 27 will encompass sales and streaming data for the Jan. 12 through Jan. 18 tracking week.

To arrive at this adjustment, Billboard charts set to post online Wednesday, Dec. 27 (following a holiday week release schedule) will be dated Wednesday, Jan. 3, one of the rare times that a Billboard chart date will not correspond to a Saturday. There is no printed issue of Billboard that week.

Below is a release/date schedule outlining this migration:

Chart date: Saturday, Dec. 30 charts posting date: Tuesday, Dec. 19
Billboard issue date: Saturday, Dec. 30 (Year-End No. 1s/double issue)

Chart date: Wednesday, Jan. 3 charts posting date: Wednesday, Dec. 27 (holiday schedule)
Billboard issue date: No Issue

Chart date: Saturday, Jan. 6 charts posting date: Wednesday, Jan. 3 (holiday schedule)
Billboard issue date: Saturday, Jan. 6
