Why Does a Daily Analytics Report Miss Records From the Previous Evening?

A daily report can miss events from the prior evening when its time window uses UTC, a local business day, or an ingestion cutoff that differs from the source system. The records may appear the next day and shift totals unexpectedly.

What to check

Compare event timestamps, ingestion timestamps, time zones, daylight-saving behavior, and the report’s inclusive and exclusive boundaries. Trace several late records through the pipeline and identify whether they were excluded or delayed.

Recommended next step

Define the reporting calendar and late-arrival policy, then make the cutoff visible to report users. Add checks for expected event coverage near day boundaries and reconcile late data consistently.
