Computed from the actual motion

The nearest Mars retrogrades either side of 1909

Previous

1907 Ended August 9, 1907 after 65 days, moving back 11.92° through the zodiac.

Next

1911 Begins October 18, 1911 and runs 72 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.
