Data Update Notice: Weekly Patterns+ Correction (Nov–Dec 2025)
7 days ago by Nolan Peters
What changed?
Advan discovered an error in the Weekly Patterns+ dataset affecting six weeks of data from early November to mid-December 2025. They reissued corrected files for this period, and those corrected weeks have now replaced the earlier (inaccurate) version in our database.
Which dates are corrected?
The following weekly periods have been updated:
- 2025-11-03
- 2025-11-10
- 2025-11-17
- 2025-11-24
- 2025-12-01
- 2025-12-08
- (plus the additional corrected week delivered by Advan covering 2025-12-14)
All data for these weeks are now consistent with the corrected export.
Why does this matter for analysis?
The previously published values for these weeks contained inaccuracies introduced during Advan’s processing. As a result, analyses may differ from any results produced using the earlier version.
If you performed analysis using Weekly Patterns+ data covering Nov–Dec 2025, you may see changes in:
- Time-series trends
- Longitudinal analyses that include these weeks
- Any statistics computed over holiday-season patterns
- Rolling averages or cumulative counts
We recommend re-running any analyses that rely on this period.
