Mars’s path through 1900, day by day
Mars starts 1900 at 12°28′ Capricorn and ends it at 10°15′ Virgo — 237.8° of net progress, all of it forward. The shaded stretch from Nov 8 is the pre-retrograde shadow: Mars is already crossing the degrees it will walk back over after turning on Jan 13, 1901. Fastest day: Feb 25, 0.79° forward. Counting the shadows, 54 days of 1900 sit inside a retrograde window.

Mars in 1900: a year between two loops
685 days separate the end of one Mars retrograde from the start of the next, and 1900 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 8, the day Mars first reaches the degree it will later retreat to.
The loops themselves are on the previous and 1901 pages.

Gap across 1900
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 1900, 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.
