Venus retrograde 1963

No retrograde period falls inside 1963. That is not an omission — the loop lands either side of the year boundary.

Why a year can have none

A retrograde recurs every 583.92 days — the synodic period of Venus. Because that does not divide evenly into 365.25 days, the loops drift through the calendar. For the slower planets a single loop can start in one year and finish in the next, leaving a calendar year with nothing inside it.

Check 1962 and 1964 — the period you are looking for will be in one of them.

Computed from the actual motion

The nearest Venus retrogrades either side of 1963

1962 Ended 3 December 1962 after 41 days, moving back 15.42° through the zodiac.

1964 Begins 29 May 1964 and runs 43 days.

Gap across 1963

1.5 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.
