How We Know the Dates
Industry trade reports, crew call sheet leaks, and standard production cycles for hourlong broadcast dramas provide the basis for this range. On-set markers such as wrap photos and legal end-credit filming notices corroborate the timeline without reliance on speculation.
Common Misconceptions
Some assume filming starts earlier or later based on promotional timelines. In reality, cast availability, showrunner planning, and network airdate commitments compress the window, especially for established series with high episode counts.
How to Verify Future Seasons
Consult authoritative outlets (e.g., ABC press releases, reputable entertainment trades) and monitor official casting announcements. These sources align with the durable production rhythm that defines long-running dramas.
