Mars retrograde in Gemini

Mars retrograde in Gemini scatters energy and sharpens arguments. Projects stall because attention is split, debates go in circles and travel plans are disrupted. It suits finishing half-done tasks and choosing which battles actually matter.

It begins in Libra season and ends in Capricorn season.

Also retrograde at the same time

  • Saturn in Taurus — Oct 18 to Dec 29, 1911 (72 days of overlap)
  • Pluto in Gemini — Oct 18 to Dec 29, 1911 (72 days of overlap)
  • Neptune in Cancer — Oct 28 to Dec 29, 1911 (63 days of overlap)
  • Mercury in Capricorn — Dec 16 to Dec 29, 1911 (13 days of overlap)

For the sign itself, see Gemini and its daily horoscope.

Computed from the actual motion

The nearest Mars retrogrades either side of 1911

Previous

1909 Ended October 24, 1909 after 62 days, moving back 11.35° through the zodiac.

Next

1913 Begins November 26, 1913 and runs 78 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.
