Warframe 1999 is surprisingly good and brings a ton of new features including the Calander system. The system is a bit confusing but don’t worry I will help you out.

Warframe 1999 Calendar system is structured system that allows you to track and participate in seasonal activities, collect rewards, and more.

The calendar is divided into four seasons, each lasting one week in real-world time. The seasons change every Monday at 0:00 UTC.

The current and upcoming seasonal timeline is as follows:

  • Winter: December 13, 2024 – December 22, 2024
  • Spring: December 22, 2024 – December 29, 2024
  • Summer: December 29, 2024 – January 5, 2025
  • Autumn: January 5, 2025 – January 12, 2025

Each season of Warframe 1999 has three months that offer unique challenges including To Dos, prizes, and Overrides linked with them.

Warframe 1999 To Dos

Each seasonal month has two tasks that you need to complete in Höllvania missions. The tasks aka To Dos are shown on your clipboard icon and reset every week.

Progress on To Dos is tracked visually; completed tasks are marked in grey while the next task is highlighted in green. You can only progress on one task at a time.

Calendar System Prizes

You take home two prizes each month from a pool of rewards. The prizes change with the seasons and are shown by a gift box icon. It’s best to claim these before the weekly reset to avoid losing them.

The items you get are randomized but usually have the following pool of rewards:

  • Arcanes – Bellicose, Truculence, Impetus, Crepuscular, Camisado, Primary Crux, Second Enervate and Melee Doughty
