How the Calendar System and Seasons work in Warframe

The Warframe 1999 update introduces a wealth of new content, including the Calendar progression system, expanded endgame narrative, and quality-of-life improvements.

Central to the update is the 1999 Calendar, a reward system tied to activities in Höllvania. The Calendar is unlocked after completing The Hex quest and interacting with the Pom-2 in key locations like the Orbiter or Höllvania Central Mall.

Warframe Calendar and Seasons, explained

In Warframe 1999, the Calendar system introduces four distinct seasons: Winter, Spring, Summer, and Autumn. Each season lasts one week in real time but spans three in-game months, affecting the environment in Höllvania. The current seasonal rotation begins with an extended Winter and follows a weekly cycle:

• Winter: Dec. 13 – Dec. 22 (January, February, March)
• Spring: Dec. 22 – Dec. 29 (April, May, June)
• Summer: Dec. 29 – Jan. 5, 2025 (July, August, September)
• Autumn: Jan. 5, 2025 – Jan. 12, 2025 (October, November, December)

Each season includes some dates of importance where players can complete certain tasks and collect limited-time rewards.
