Sunday 6 December 2026. Mercury moves to Sagittarius.

Mercury changes sign. A good point to change how you write up and talk through plans. Where it lands depends on your chart: the same degree is someone’s 10th house and someone else’s 4th.

  2. 02 · At work

    Say the big idea out loud

    Mercury is about messages, plans and paperwork. Sagittarius is about learning, publishing and the bigger picture. It's a prompt to share the idea you've been holding and to sketch next year in broad strokes.

  3. 03 · One move

    Write a one-page plan

    Before the end of December, write one page on where you want your work to go next year. Keep it to three goals, with one first step for each.

Where 0° Sagittarius lands in your chart

Your chart has twelve houses, and 0° Sagittarius sits in one of them. For one person that’s the money house. For someone else it’s daily work, or home. Your birth date, time and place decide which.

Each house ties the date to a different part of your work. Houses 2, 6 and 10 are the work houses: income, daily work and your public role.
