Sagittarius season gets sold as pure relief: truth, freedom, the big laugh. Read the ingress chart and you get something more useful. The theme is plain speech under pressure, not a smooth miracle of honesty.

The tightest contact in the sky at 07:23 UTC is the Moon at 28.35° Aries trine Mars at 28.50° Leo, an orb of about 0.15°. That is drive with almost no gap between impulse and action. It feels like the moment you already know what you want to say.

The Sun's contact with Mars is the engine of the season. At 0° Sagittarius the Sun sits 1.50° past an exact square to Mars in Leo. That is a separating square — friction that has already peaked and is now unwinding through you. The irritation is in the room on day one. Your job is to name it, not to let it leak out sideways over the following weeks.

Scorpio rewarded you for phrasing things carefully. Sagittarius expects the stripped version. So what actually changes at 0°? The editing stops being rewarded. The careful version you have been polishing stops reading as tact and starts reading as evasion.

Two slower contacts add structure. Saturn at 8.24° Aries is retrograde and trines the Sun at a wide 8.24° orb; that brings the demand to give your plain answer a plan attached. Mercury at 10.58° Scorpio and Venus at 24.18° Libra are not the closest majors to the Sun, so this month's candour is Mars-driven — direct, a little hot — rather than carefully diplomatic.

Here are the themes, tied to what you will actually feel.

Truth as action. The Moon–Mars trine supports doing the thing you keep describing. Send the message. Book the call. Say the number out loud.

Candour with an edge. The separating Sun–Mars square means friction present from minute one. Expect short tempers and blunt replies. Use that heat as a signal for what needs saying, not as permission to burn down a room.

Structure over drama. Saturn's wide trine to the Sun rewards a clear sentence with a next step behind it. "I want X, and here is how we start" lands better than a grand confession with no follow-through.

Heat, once used, moves on. That separating square is unwinding through you, not waiting for you to handle it. If you spend the first two weeks silent, the friction goes elsewhere — a snapped email, a door closed too hard, an argument about the wrong thing.

This is a degree-contact list, not a prediction about people. Sagittarius carries the Sun at 0°. Leo carries Mars at 28.50°, the square's tight end. Aries carries the Moon at 28.35°, whose near-exact trine to Mars opens the month, with Saturn retrograde at 8.24° in the same sign. Libra is where those square and trine degrees land when measured from the other side of the zodiac. If your own placements sit near these degrees, the season speaks to you directly; if they do not, it passes at a distance.

That settles your first question. What changes at 0° is the reward structure: careful phrasing loses value, plain phrasing gains it. What stays the same is the unresolved answer — and the heat already in the room. Next, the exact degrees that decide whether this month touches your chart or just passes near it.

The degrees decide whether this season lands on you or merely passes nearby. A seasonal ingress means nothing personal until a transiting planet reaches a degree that activates one of your own placements. The ingress degrees give you the list to check.

Start with 0° Sagittarius. Any natal point sitting within a degree or two of that boundary — Sun, Moon, rising sign, Venus, a planet, a chart angle — takes the Sun's arrival directly. That is where the plain answer becomes hardest to dodge, and where the separating Sun–Mars square shows up as a real, specific irritation rather than background noise.

An example makes it concrete. If your Moon sits at 1° Sagittarius, the season opens on it, and the first two weeks feel like being handed a microphone you did not ask for. If your Mercury sits at 11° Scorpio and your Venus at 24° Libra, neither sits near the ingress point or the Mars square, so the candour pressure runs softer for you. The season is loud in your life; where it is loud depends on your degrees.

The 8°–10° window on the Saturn row deserves its own thought. Saturn moves slowly and is retrograde here, so a natal point near 8° Aries or 8° Libra stays in contact for weeks, not days. That is where the plan behind your plain answer gets tested — and where postponement gets expensive.

Reading a chart is abstract until it turns into a sentence you actually say. Here are four scenes built from the ingress degrees. Take the one that stings a little.

The work situation. You have been telling your manager the project is "mostly on track." Mars in Leo at 28.50° squares the Sun, and that square is separating — the friction is already there. The Sagittarius version is: "One deliverable will slip by a week. I need the deadline moved or a second pair of hands." Plain, specific, no apology paragraph attached. Saturn's wide trine to the Sun backs the version with a plan inside it.

The friend who overstepped. You said nothing in Scorpio season and called it keeping the peace. If the Sun at 0° Sagittarius lands near your own Sagittarius placement, the season hands you the microphone. Try: "What you said at dinner sat badly with me. I want to clear it rather than carry it." The near-exact Moon–Mars trine at 0.15° supports saying it early, while the impulse is fresh, instead of letting it age into resentment.

The number you have been rounding. A budget, a quote, a shared bill. Mars heat pushes you to blur it or inflate it. Saturn in Aries, retrograde at 8.24°, asks for the precise figure and the date it lands. "It comes to £340, and I can send it Friday" is more Sagittarian than a warm vague promise.

The conversation you keep pre-writing. If you have drafted the message five times, the square has already done its work on you. The Sagittarius move is to send the version you would say out loud, not the version engineered to survive every possible reaction.

One caution on the heat. A 1.50° separating square can read as a licence for bluntness that costs you something. Candour with an edge still has an edge — keep the fact plain and the blame minimal.

Before you spend the month reacting, check whether the season is actually meeting your chart — that is the third thing the degrees answer, and the next section shows the fastest way to get it.

The season closes on December 20, 2026, when the Sun leaves Sagittarius. You have roughly four weeks between the ingress and that exit to say the plain version out loud. That window is the whole point of the month.

Work backwards from it. Give yourself the first two weeks for the hardest sentence — the one carrying the separating Sun–Mars square. If you spend that fortnight silent, the friction does not vanish; it goes sideways into a snapped reply about something smaller.

Then let Saturn's slower message settle in. Saturn at 8.24° Aries is retrograde, trining the Sun at a wide 8.24° orb. That is the second half of the season: attaching a plan, a date, a number to the answer you delivered. Plain speech without follow-through is just noise in a louder key.

One assumption to drop. The Moon is not in a major aspect to the Sun at the ingress. At 28.35° Aries the Moon sits 148.35° from the Sun, and the nearest major aspect, a trine, carries a 28.35° orb — far too wide to count. So do not build the month's story around emotional ease. Build it around the sentence you have been editing.
