The Season 3 reunion in question does not have an officially confirmed filming date, but credible entertainment outlets and fan sleuthing place the filming in early fall 2025, most likely between September and October 2025.

Quick Scoop

  • The Season 3 reunion for The Secret Lives of Mormon Wives appears to have been shot months before it aired, during the production overlap between Seasons 3 and 4.
  • Reports note that Season 2’s reunion was filmed in April 2025 while Season 3 was already shooting, and clues suggest the Season 3 reunion followed a similar pattern later in 2025.
  • Because ongoing storylines and recent social-media drama were missing from the special, many viewers concluded the reunion was filmed before late‑2025 events, supporting a September–October 2025 estimate.

What sources say

  • One detailed breakdown explains that Hulu and the cast have not released an exact date, but production and storyline clues narrow the window to early fall 2025, likely between September and October.
  • Another outlet, looking at filming schedules and cast interviews, estimates the Season 3 reunion was filmed sometime between August and November 2025, probably as Season 4 cameras were already rolling.

Why the timing matters

  • Fans noticed that big late‑season or very recent real‑life developments (“buzzy” social media arcs, newer scandals) were not addressed at all in the reunion, making it feel more like a bridge into Season 4 than a true Season 3 wrap‑up.
  • This mismatch between air date and filming date has become a trending forum and social topic, with many discussions focusing on how back‑to‑back production affects the authenticity of reality‑TV reunions.

Mini timeline (approximate)

  • Season 2 filmed: roughly October–December 2024.
  • Season 3 filmed: roughly March–May 2025.
  • Season 2 reunion: around April 2025 (during Season 3 filming).
  • Season 3 reunion: most likely early fall 2025, between about September and October, during or just before Season 4 filming.

Bottom line: there is no exact public date, but all available evidence clusters the Season 3 reunion filming in early fall 2025, not close to its December release.

TL;DR: When was Season 3 reunion filmed?
Likely in early fall 2025 (around September–October), during overlapping production with Season 4, which is why it skips some late 2025 drama.
