Computed from the actual motion

The nearest Mars retrogrades either side of 1939

Previous

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

Next

1941 Begins September 6, 1941 and runs 65 days.

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.
