Season ended This Diablo III season has ended. The next season's dates appear here as soon as the publisher confirms them.
No official end date exists yet, so the figure above is projected from this game’s own past seasons and carries an EST. tag until the publisher confirms one.
Every date is re-checked nightly. Historical cadence is context only — an official date always replaces an estimate, the same day, and the correction records what the date was changed from.
Diablo III Season 39: Shades of the Nephalem is estimated to end around September 25, 2026, based on its 90-day season cadence (verified September 4, 2026). Season 39: Shades of the Nephalem launched June 27, 2026 (5:00 PM PDT on June 26), reviving the theme that first debuted in Season 22: a 4th Kanai's Cube slot and the Shadows of the Past shrine-clone buff.
Diablo 3 Season 39: Shades of the Nephalem launched June 27, 2026 (5:00 PM PDT on June 26), bringing back the Shades of the Nephalem theme first introduced in Season 22. Blizzard has not announced an end date — the countdown above tracks a cadence-based estimate until the next season is confirmed.
Based on the last four seasons' lengths (79–107 days), Season 39 is estimated to end in late September 2026, with Season 40 following in early October. Blizzard typically confirms the exact transition only a few days ahead.
Recent Diablo 3 seasons: Season 38: Ethereal Memory ran 86 days (Mar 27 – Jun 21, 2026), Season 37: The Forbidden Archives ran 107 days (Dec 5, 2025 – Mar 22, 2026), Season 36: The Lords of Hell ran 79 days (Sep 12 – Nov 30, 2025), and Season 35: Eternal Conflict ran 93 days (Jun 6 – Sep 7, 2025).
Season length varies from about 11 to 15 weeks depending on content scope, which is why the site tracks an estimate rather than a fixed countdown until Blizzard confirms the reset.
Season 39 reintroduces the Shades of the Nephalem theme: a 4th Kanai's Cube slot lets players equip a second power from one of the Weapon, Armor, or Jewelry categories, on top of the usual three.
The seasonal buff, Shadows of the Past, spawns a scaling AI-controlled shadow clone of your class when you activate a Shrine or Pylon, running one of three randomized builds for 60 seconds to boost damage and survivability.
