Mars in 1927: a year between two loops
706 days separate the end of one Mars retrograde from the start of the next, and 1927 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 January 31, when Mars is back at the degree where it first turned.

Gap across 1927
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 1927, 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.
