Venus retrograde 1965

No retrograde period falls inside 1965. 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 1964 and 1966 — the period you are looking for will be in one of them.

Computed from the actual motion

The nearest Venus retrogrades either side of 1965

1964 Ended 11 July 1964 after 43 days, moving back 16.52° through the zodiac.

1966 Begins 5 January 1966 and runs 41 days.

Gap across 1965

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.
