Short answer
On 5 Dec 2026, Rahu moves from Kumbha into Makara and Ketu from Simha into Kataka, staying about 18 months. For you, attention shifts to the two houses Makara and Kataka occupy from your Moon sign: Rahu marks where you feel hungry and restless, Ketu where you let go. Almanacs using the true node give about 25 Nov 2026.
How ChiChakra reads this
Rahu and Ketu are the lunar nodes (the two points where the Moon's path crosses the Sun's), always exactly opposite each other. ChiChakra uses the mean node, which gives 5 Dec 2026; true-node calendars show the change about ten days earlier. Both are recognised conventions, so check which one a calendar follows before comparing dates.
What the shift may bring
Count from your Moon sign. For a Makara Moon, Rahu sits on your Moon and Ketu in the 7th, so self-image and partnerships come into focus; for a Kataka Moon it is the other way round.
Rahu traditionally brings ambition, new interests and sometimes overreach; Ketu brings detachment, inner work and a wish to simplify. Read both ends together, because what you chase in one area often draws attention from the other.
In practice: notice where you suddenly feel driven, pause before big impulsive moves, and release what has run its course. The axis returns to the same place about every 18.6 years.
Good to know
Where Rahu and Ketu sit in your birth chart, and whether you are running a Rahu or Ketu Dasha (planetary period), shape this far more than the sign change alone.
