Mars retrograde in Leo

Mars retrograde in Leo tests pride, ambition and creative drive. Plans for recognition stall, conflicts with authority figures flare, and people reconsider what they are fighting for. It suits reworking creative ambitions rather than forcing them.

It begins in Sagittarius season and ends in Pisces season.

Also retrograde at the same time

  • Mercury in Capricorn — Dec 26 to Jan 15, 2010 (20 days of overlap)
  • Saturn in Libra — Jan 13 to Mar 10, 2010 (56 days of overlap)

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

Computed from the actual motion

The nearest Mars retrogrades either side of 2009

Previous

2008 Ended January 30, 2008 after 77 days, moving back 18.37° through the zodiac.

Next

2012 Begins January 24, 2012 and runs 81 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.

Computed for 2009
