Computed from the actual motion

The nearest Mercury retrogrades either side of 1964

Previous

Gap across 1964

1.2 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.
