Sun–Moon Synastry
Sun–Moon synastry is one person's identity meeting the other's need to feel safe. The Sun wants to be seen. The Moon wants a private weather. Both birth times are required. This contact belongs to two birth charts, not to one.

The Moon changes signs about every two and a half days, and it moves about a degree every two hours. Both birth times are required. A birthday cannot place this angle. One person's Sun on the other's Moon is the classic “I feel like myself around you” contact. The reverse, Moon on Sun, is the other person feeling seen in their private weather. They can both be present. They are not the same sentence. Orbs widen by about a degree and a half when the Sun or Moon is one of the two planets. A wide orb is a weaker contact.
Conjunction
A Sun–Moon conjunction in synastry puts one person's face against the other's need. The Moon person often feels recognized without a long explanation. The Sun person feels their way of being alive has somewhere to land. Home and identity share a temperature, which is why this contact is famous and why it can crowd a house. There is little gap. A slight to the Sun lands on the Moon. A mood from the Moon changes the Sun's whole afternoon. When the Sun person's light is the Moon person's safety, the bond feels like kinship early. The reverse is just as strong and less often named: the Moon person supplies the weather, and the Sun person starts to need that weather in order to feel like themselves. Family notices. Friends say the pair makes sense in a room. The hard part is the missing interior argument between them. They can confuse “this is who you are to me” with “this is what I need,” and steamroll a quieter hour because the conjunction did not keep a back room. One of them may perform the life while the other feels it, and both call that balance. Use the recognition. Leave one feeling that is allowed to be smaller than the identity, and one ambition that does not have to soothe the house. The people in this conjunction need an hour that is not also a merger. A natal Sun–Moon aspect inside either chart is that person's private split or private unity. Synastry is what happens when one chart's Sun meets the other chart's Moon.
Square and opposition
The square and the opposition set one person's aim against the other's need to feel safe. The life the Sun is building shames, interrupts, or simply misses the Moon's weather. A goal arrives as a mood. A mood undercuts a plan. The pair can look inconsistent to anyone who meets them on one kind of day. The square is the jam inside the week they share. Friction is close: a trip the Sun needs and the Moon experiences as exile, a family duty the Moon needs and the Sun experiences as a smaller life. It is hard to outsource, because both charts are in the argument. The opposition stretches the same argument across a distance. One person lives the solar role in public. The other becomes the private life, the home, the parent-shaped mood, and then resents the casting. Or the Moon person keeps the house and the Sun person keeps leaving it in order to be seen. The square irritates until the two halves share a schedule. The opposition keeps finding the missing half in the partner until each person claims both a name and a feeling. Neither aspect means the bond is a mistake. Both mean identity and safety do not arrive as one gift between these charts. Birth time still decides whether the angle is there. A few hours of error on the Moon can invent a square the sky did not make, or erase one it did. The useful version puts the aim and the mood on the same calendar without making one of them the servant.
Sextile and trine
The sextile and the trine let one person's identity and the other's safety talk without a standing fight. The Moon person can be around the Sun and still feel like themselves. The Sun person can be seen without exiling the private life that the Moon is holding. Feeling informs the role. The role does not have to be performed at home in the same voice. Other people experience a pair that is readable without being raw. The sextile is a door. The mood can correct the performance, and the aim can give the mood a direction, if someone bothers. Unused, it looks like a comfortable household that never quite chose each other on purpose. The trine is the agreement arriving as temperament. They already match, so they may never notice the gift until they meet a pair with a hard Sun–Moon and see the fight they did not have to have. The trine differs from the sextile because it does not ask to be practiced. Harmony can stay unconscious. They may assume every bond can live at home inside a name, and they can under-use a talent that would have made a public life and a private life the same house on purpose. Ease is real between these two charts. It is not a reason to skip the conversation about which person is tired of being the Sun, and which is tired of being the Moon. The sextile can still be ignored. The trine can still be asleep.

The angle is calculated from both birth dates, times, and places. A Sun sign does not name it.
