Mars in 1938: a year between two loops

725 days separate the end of one Mars retrograde from the start of the next, and 1938 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 loops themselves are on the 1937 and 1939 pages.

Computed from the actual motion

The nearest Mars retrogrades either side of 1938

Previous

1937 Ended June 27, 1937 after 74 days, moving back 16° through the zodiac.

Next

1939 Begins June 22, 1939 and runs 62 days.

Gap across 1938

2 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.

Mars through the zodiac in 1938

Every sign Mars occupies during 1938, 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.
