Mars in 1912: a year between two loops

698 days separate the end of one Mars retrograde from the start of the next, and 1912 falls entirely inside that stretch. Mars turns back once every 779.94 days — longer than a calendar year — and each loop is over in weeks, so now and then a whole year passes between two of them.

The year opens inside the tail of the previous loop: its post-retrograde shadow closes on February 27, when Mars is back at the degree where it first turned.

The loops themselves are on the 1911 and 1913 pages.

Computed from the actual motion

The nearest Mars retrogrades either side of 1912

Previous

1911 Ended December 29, 1911 after 72 days, moving back 16.66° through the zodiac.

Next

1913 Begins November 26, 1913 and runs 78 days.

Gap across 1912

1.9 years between the two — long enough for a whole calendar year to fall inside it with nothing to report.

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.

Every sign Mars occupies during 1912, with the dates it enters and leaves. A sign that appears twice means the planet backed into the previous sign during a retrograde and crossed again.
