Mars’s path through 1917, day by day
Mars starts 1917 at 22°09′ Capricorn and ends it at 25°54′ Virgo — 243.8° of net progress, all of it forward. The shaded stretch from Nov 29 is the pre-retrograde shadow: Mars is already crossing the degrees it will walk back over after turning on Feb 3, 1918. Fastest day: Feb 13, 0.79° forward. Counting the shadows, 33 days of 1917 sit inside a retrograde window.

Mars in 1917: a year between two loops
684 days separate the end of one Mars retrograde from the start of the next, and 1917 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 run-up to the next loop starts before the year is out: the pre-retrograde shadow opens on November 29, the day Mars first reaches the degree it will later retreat to.

Gap across 1917
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 1917, 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.
