Retrograde Calendar 2027 — Every Planet, Exact Dates

Every retrograde of 2027 across Mercury, Venus, Mars, Jupiter and Saturn, with exact start and end dates computed from each planet's apparent motion.

The fast planets

Mercury retrogrades about three times a year for three weeks; Venus roughly once every eighteen months for six. These are the ones people notice, because they touch conversation and money.

Mars

Mars reverses only about every twenty-six months, so whole years pass without one. When it does, tradition reads it as anger turned inward and momentum that will not convert.

The slow planets

Jupiter and Saturn spend four to five months of every year retrograde. Because it is nearly half of all the time, it makes little sense to treat it as an emergency — it is closer to the planet's inward season than an event.

Why the Sun and Moon never do

Retrograde is a trick of relative motion between Earth and another body orbiting the Sun. The Sun is what we orbit and the Moon orbits us, so neither can appear to reverse. Rahu and Ketu are the mirror case — they are always retrograde by definition.

Reading them together

A retrograde only matters to you if it touches something live in your chart. Mercury retrograde in a quiet corner of your kundli will pass unnoticed; over your Moon it will not.
