Mars retrograde in Scorpio

Mars retrograde in Scorpio intensifies power struggles and buried anger. Old conflicts resurface, obsessions deepen and control becomes the issue. It suits deep inner work and releasing grudges rather than launching aggressive campaigns.

…and back into Libra

Mars retrograde in Libra brings conflict in partnerships to the surface. Unspoken resentments emerge, legal disputes slow down and decisions stall under indecision. It suits renegotiating fairness rather than escalating disagreements.

It begins in Pisces season and ends in Gemini season.

  • Mercury in Aries — Mar 15 to Apr 2, 1920 (19 days of overlap)

Computed from the actual motion

The nearest Mars retrogrades either side of 1920

Previous

1918 Ended April 25, 1918 after 81 days, moving back 19.22° through the zodiac.

Next

1922 Begins May 8, 1922 and runs 70 days.

Both dates are computed from the planet’s apparent motion, not taken from a table. A retrograde begins the moment its daily movement against the stars turns negative, and that moment is findable to the hour.
