Mars Retrograde Calendar
You're checking when Mars is retrograde, and this calendar gives you exactly that — every Mars station across your date range, filtered down from the full retrograde list. Mars retrograde is rarer and longer than Mercury's, so this list will typically show far fewer, more spread-out windows.How it works ↓

Mars turns retrograde roughly once every two years, for about two to two-and-a-half months at a stretch, far less often than Mercury, but with a longer, more intense arc. It's traditionally tied to frustrated action, revisited conflicts, and delayed momentum.
Mars retrograde is also an optical effect, not a real reversal
Mars keeps orbiting the Sun in the same direction the entire time. Because Earth orbits faster than Mars, there are stretches where Earth's own motion overtakes Mars in its orbit, making Mars appear to slow, stop, and drift backward against the stars before resuming forward once Earth pulls ahead.
It's the same relative-speed effect behind every retrograde in this calendar — Mars just does it far less often, and each occurrence lasts much longer.
The least frequent, longest-lasting retrograde of the inner planets
Mars turns retrograde roughly once every two years, and when it does, the retrograde itself runs about two to two-and-a-half months — 60 to 80 days. That's a much longer single stretch than Mercury's three weeks or Venus's 40 days, even though Mars retrogrades far less often than either.
Because it's this infrequent, a Mars retrograde window is worth flagging well in advance if you're planning something time-sensitive during it.
Traditionally tied to frustrated action and re-litigated conflict
Mars governs assertion, drive, and direct action, so its retrograde is traditionally read as a period where momentum stalls, disputes that seemed settled resurface, and starting something new meets more resistance than usual. The longer duration compared to Mercury or Venus is part of why this retrograde has a reputation for feeling more drawn-out.
The traditional read isn't that action is impossible during this window — more that it favors finishing and revisiting over launching something brand new.
Shadow periods stretch Mars's influence over additional weeks
Like every retrograde, Mars has a pre-shadow and post-shadow — the stretches before and after the retrograde where it crosses the same degrees again. Given how long the retrograde itself already runs, Mars's shadow periods extend an already lengthy window even further.
Traditional practice treats these as a gradual build and fade rather than a hard switch at the exact station date.
Mars retrograde compared to Mercury and Venus retrograde
Mercury retrogrades three to four times a year for about three weeks each. Venus retrogrades roughly every 18 months for about 40 days. Mars is the outlier: roughly once every two years, but for two to two-and-a-half months once it happens — the least frequent of the three, and the longest-running when it does occur.
If you want all three planets side by side, the full retrograde-calendar shows Mercury, Venus, and Mars together along with the outer planets.
Frequently Asked Questions
How often does Mars go retrograde?
Roughly once every two years, with each retrograde lasting about two to two-and-a-half months — far less often than Mercury or Venus, but for a longer stretch each time.
What does Mars retrograde mean for conflict and decisions?
Traditionally it favors revisiting and finishing over starting new — disputes that felt resolved can resurface, and new initiatives may meet more friction than usual until Mars stations direct.
How long does a Mars retrograde shadow period last?
It varies by cycle, but because the retrograde itself runs two to two-and-a-half months, the pre- and post-shadow periods extend Mars's influence for additional weeks on either side.
