What the seventh house covers
The seventh house begins at the Descendant, the point on the western horizon at the moment you were born. The first house is you, alone, walking into the room. The seventh is whoever is waiting on the other side of the table. In practice that means a spouse or long-term partner, but also a business partner, a solicitor, a landlord, a regular client, a co-parent, or the person you are suing. Anyone with whom you have a one-to-one arrangement, formal or informal, belongs here.
It also covers contracts and agreements, because a contract is simply a relationship written down. And it covers open rivals, the competitor you can see and name, as opposed to hidden enemies, who belong to the twelfth house.
What the Sun does when it passes through
The Sun in transit brings vitality and visibility to whatever house it is in. Life there gets lit up, and it asks for conscious attention and a bit of pride. In the seventh house that light falls on the other person rather than on you. Your partner's needs, moods and plans become more noticeable. If you are single, the question of partnership itself comes up more often, even if only in your own head.
Because the Sun is about identity, the deeper theme is learning who you are in relation to someone else. Where do you give way, where do you hold your ground, and what do you actually want from a partnership. None of that has to become dramatic. Mostly it shows up as a month where relationships take up more room in your diary and your thoughts than they did in the month before.
How it usually feels
Many people notice a mild shift of emphasis. You find yourself saying yes to a dinner with your partner's family that you would normally dodge. A client who has been quiet for months gets in touch and wants a meeting. A tenancy agreement or freelance contract comes up for renewal and needs reading properly. A disagreement you have been sitting on gets aired, not because anything blew up, but because it was suddenly easier to talk about.
There is also a social quality to it. The Sun in the first house makes you self-sufficient; in the seventh it makes you want company and a mirror. You may feel less sure of yourself alone and more alive in conversation. That is normal, and it passes when the Sun moves on into the eighth house.
When it happens for you
The Sun moves about one degree a day, so it takes roughly a month to cross a house of average size. It enters your seventh house on the same dates every year, give or take a day, because the Sun's cycle is the calendar year. If you know the sign on your Descendant, you know when to expect it: the Sun is in your seventh house while it moves through that sign and, if the house is wide or narrow, a bit more or less.
If your natal Sun sits in the seventh house, the transit coincides with your birthday and your solar return each year. For you the yearly stock-take of who you are is always tied up with who you are with, and the month carries more weight than it does for most people.
Who feels it more strongly
The transit is gentle for most people, a climate rather than an event. It is stronger if you have natal planets in the seventh house, because the Sun will pass over each of them in turn and switch them on for a few days. A conjunction with natal Venus there tends to bring warmth and attention from a partner; passing over Saturn there can make a relationship feel like work for a week.
It is also stronger if the transiting Sun forms tight aspects to other planets in your chart while it is in the seventh house, or if a slower planet such as Saturn, Jupiter or Pluto is also moving through your seventh house at the same time. In that case the Sun acts as a trigger, bringing a longer theme to a head for a few days. The whole chart matters, and a Sun transit on its own rarely decides anything.

Areas of life
Couples usually find the relationship takes more of their attention, for good or ill. It is a natural month to plan something together, have the conversation you have been postponing, or simply notice your partner more clearly. Single people often feel the pull toward pairing up more sharply than usual, and other people may seem more interested in you because you are more open to being met.
Work becomes more about one-to-one dealings than solo effort. Client meetings, negotiations, partnerships and pitches go better when you prepare for them. A visible rival may step forward, which is useful information rather than a threat. If you run a business with someone, the balance of the partnership tends to come up for review.
The money side of the seventh house is contracts and joint arrangements. Read anything you are asked to sign, from a lease to a freelance agreement, and ask about the parts you do not understand. Shared costs with a partner may need a frank conversation, and it is a fair month to have it.
If you live with a partner, decisions about the flat or house tend to become joint decisions rather than assumptions. Who does what, who pays what, and whether to stay or move can all surface. Living alone, you may feel the quiet more and want visitors.
Friendships that work as pairs, the one friend you always meet for coffee, get more of your time than group gatherings. You may also mediate between two other people, or find a friend leaning on you for help with their own relationship. Say yes when you can and no when you cannot.
What to do with it
- Give your partner, business or romantic, some undivided attention this month. Put the phone away for one proper conversation a week.
- Read every contract before you sign it, and ask for a day to think if you feel rushed.
- If there is a disagreement you have been avoiding, raise it now, calmly, while talking feels easier.
- Notice where you are bending too far to keep the peace. The Sun here asks for partnership, not disappearance.
- Treat an open competitor as a source of information. Look at what they do well and what you would not do.
- Do not decide the future of a relationship on the strength of one bright or one difficult week. Wait until the Sun has moved on and see how you feel then.
