Updating usually occurs on the 15th of each month,…

Not quite. I have a job that runs every day, downloads the RRS and IND data files (data, not graph) and also keeps track of the “Last Updated” field. It also saves the file, with the date embedded in the filename. It has the data since early 2016.

Anyway… here is the distribution of the day numbers of the updates:


Advance Real Retail and Food Services Sales
Series ID:  RRSFS

  Count Day of month
      1 01 
      1 02 
      1 05 
      1 10 
      2 11 
      5 12 
      7 13 
     19 14 
     26 15 
     21 16 
      8 17

      2 19 
      1 23 
      1 26 

Industrial Production: Total Index
Series ID:  INDPRO

  Count Day of month
      1 01 
      9 14 
     28 15 
     18 16 
     20 17 
      4 18 
      1 27 
      3 28 
      1 31

The dates late in the month are usually the second release in a month, with revised value(s). The dates early in the month are usually preliminary, and will be revised/updated later in the month.

If you want to look at the data only once per month, you should wait until the 18’th of the month or later.
