Reading: today (transit) · valid while the transit lasts, not for life
Some mornings you wake up ready to take on everything: the overdue report, the closet that needs emptying, the run you’ve been putting off since the summer. Other mornings, a car that’s slow off the line at a green light is enough to make your blood pressure spike. Sleep, stress and caffeine all play their part. Astrology offers one more factor, as regular as a calendar: the Sun passing over the Mars you were born with.
What happens between the transiting Sun and your natal Mars
In your birth chart, Mars describes how you act. Your physical energy, your desire, your courage, the way you stand up for yourself when someone steps on your toes, what makes you angry and what you do with that anger. It’s the planet that gets things started, the one that turns a wish into a first step. The page on Mars in astrology has the full picture.
The Sun and Mars have something in common: both are planets of self-assertion. The Sun says who you want to be, and Mars goes out and gets it. When the Sun in the sky forms an aspect to your natal Mars, astrologers call it a transit, and it’s a bit like blowing on embers. Your energy rises, so does your drive, and your patience drops by the same amount. Depending on the angle, that surplus turns into momentum or friction.
The sign of your natal Mars sets the tone. A Mars in Aries or Scorpio, its two home signs (its domicile), lives these passes in a direct, intense way. A Mars in Libra or Taurus, the signs of its detriment, acts more slowly or goes the diplomatic route, and the Sun helps it dare. A Mars in Capricorn, its sign of exaltation, turns that energy into stamina. If your Mars is retrograde in your chart, your way of acting often matures inside before it shows; you’ll find more in Mars retrograde in the natal chart.
Many astrologers treat fast transits over Mars as triggers. They give the push that sets in motion whatever was already ripe. The backdrop is still painted by your slow transits.
How long the transit lasts
The Sun moves about one degree a day. Each aspect to your natal Mars lasts a few days, peaking on the day the angle is exact. The Sun never goes retrograde, so it crosses each point only once and keeps going.
Over a year, your Mars meets the Sun eight times: one conjunction, one opposition, and two each of the sextile, square and trine. The dates come back almost unchanged every year.
Unlike Mercury or Venus, Mars can sit anywhere in relation to your natal Sun. The conjunction might land in the middle of winter for someone born in summer. If your Mars is close to your Sun, it arrives around your birthday, and your new year starts at full throttle every time.
The conjunction: the engine at full revs
The Sun joins your natal Mars. For a few days, your urge to act, decide and test yourself against something moves to the front.
Whatever has been stuck for weeks no longer scares you. Calling the landlord about the leak, getting back to the gym, finally sending in your application, defending your view in a meeting without apologizing three times. Your body wants to move, and long hours in a desk chair start to feel like a sentence.
Impatience rises to match. A line that won’t move, a coworker who disagrees just for sport, a traffic jam on the freeway: anything that slows you down gets under your skin. Ryan notices it every year around the same time. On conjunction days he runs twice as far, finishes projects he started months ago, and snaps a little at his brother on the phone.
To use it, give that energy a job before it finds one on its own. A physical effort, a concrete project, a decision to make. You’ll feel this push again next year on the same date; this time, choose where to aim it.
The sextile: a window to act
Twice a year, the Sun forms a sextile, a 60-degree angle, to your natal Mars. A little effort is all it takes to turn these days into an opening.
You feel like getting things moving, and in a group you’re often the one who gives the signal. Organizing the HOA meeting nobody wants to call, finally assembling the bookshelf that’s still in its box, talking two friends into a hike. On these days, whatever you start with other people moves fast.
When you ask for something, get to the point. A simple “Can you get back to me by Friday?” gets further than a long, polite detour.
Nothing about the mood is urgent. These few days are an open window, worth using if you have something to launch; if not, the sextile will pass quietly.
The square: things heat up fast
Twice a year, the Sun squares your natal Mars. Your will and your energy grind against circumstances.
Your inner tempo outruns the world’s, and anything that pushes back gets on your nerves. It’s the kind of stretch where people fire off an email in a tone they regret, cut others off mid-sentence, or push a knee that needed a warm-up. Behind the wheel and at the gym, caution is worth its weight in gold: rushing costs more than usual.
Take Megan. On a Tuesday during a Sun square Mars, her manager pulls her off a project without explanation. She feels the anger rising, drafts a scorching reply and, instead of sending it, goes for a twenty-minute walk. When she comes back, she asks for a meeting and calmly explains why the project should stay with her. She gets it back, and she keeps her cool doing it.
How to use it: build a real physical workout into your week, break big tasks into small pieces, and sleep on anything that stung before you answer. That irritation has its uses too: it often supplies the energy that was missing to settle a question that’s been hanging for weeks.
The trine: action without forcing
Twice a year, the Sun supports your natal Mars by trine, a 120-degree angle. What you want and the energy to do it show up at the same time.
You act almost without thinking about it. You add a mile to your run, open the most dreaded file first thing Monday, finally ask your neighbor whether she’d feed the cat in August. You say what you want in a calm voice, and people listen more readily.
If you have a long-haul project in mind, these days are ideal for starting it: a running plan, a renovation, a skill you’ll have to stick with. The energy of the start matters a lot, and the trine provides it without pushing you to overdo it.
The trap is believing everything will stay this easy. For a few days the energy is there without effort; plan now how you’ll keep going once it’s back to normal.
The opposition: a tug of war
Once a year, the Sun sits opposite your natal Mars. Other people push your buttons.
Someone needles you, upstages you or piles on the pressure, and you itch to hit back right away. A coworker takes credit for your idea, a neighbor blocks your driveway, a teenager slams the door just as you get home running on empty. And sometimes, without noticing, you’re the one speeding everyone up, until their annoyance comes back at you like a boomerang.
During these days, the way you handle conflict becomes very visible. Do you charge ahead, give in to keep the peace, or stew in silence? Every reflex has its reasons; the opposition puts yours in the spotlight.
Kevin goes through this opposition during a contract negotiation. The other side pushes him to accept a huge discount. His first instinct is to walk out. He asks for a break, comes back with three clear conditions, and holds his ground without raising his voice. The final deal works for him.
How to use it: burn off the energy through exercise, negotiate firmly and calmly, and state your disagreement clearly rather than letting it blow up later. After a few days the Sun moves on and the air clears.
Frequently asked questions
Is the Sun square my natal Mars dangerous?
It doesn’t predict any accident or any certain fight. It points to a few days when your patience is shorter and your energy edgier. Easing off the gas pedal, warming up before a workout and waiting before you reply in the heat of the moment are enough to avoid most of the damage. Well channeled, that energy can even help you unstick what had stalled.
How is this different from transiting Mars over my Sun?
They’re two different transits. Here, it’s the Sun in the sky touching your natal Mars: the pass lasts a few days and comes back every year. When Mars passes over your natal Sun, the contact comes back roughly every two years, lasts longer, and can stretch over weeks if Mars is retrograde at the time. To understand that, read Mars retrograde.
When does the Sun cross my natal Mars this year?
You need the sign and degree of your Mars, which your calculated birth chart gives you. The Sun hits that degree on the same date every year, give or take a day. To round out the picture, also look at the Sun’s passes over your natal Venus and your natal Jupiter, at the Sun transiting your 1st house, the area of self-assertion, and at the page on the 1st house.
