What Season 10 was
Season 10 was called Season of Infernal Chaos. Blizzard’s season announcement gives September 23 as the date and describes Chaos Armor, Chaos Perks and Chaos Rifts. It also outlines permanent Infernal Hordes updates for both Seasonal and Eternal Realms, including Chaos Waves and Bartuc as a boss. Blizzard’s announcement states the date but does not give a launch hour; the precise time and regional conversions above are reported by Icy Veins.

Why the date is in the past
Season 10 is no longer upcoming. In a Blizzard-authored Xbox Wire article dated September 24, 2025, Chelsea Leah said the season was available that day. Blizzard’s September 30, 2026 patch notes show the game had moved on to later seasonal content.
