No birth time? Here’s what your chart still says
Without a birth time you lose the rising sign, the houses and the Midheaven. You keep the Sun, the Moon and eight planets by sign, and every aspect between them, which is most of what a reading is made of.

What needs the time
The rising sign changes roughly every two hours, because it is the sign on the eastern horizon and the horizon sweeps through the whole zodiac each day. Without a time it is unknowable; a noon guess is wrong about eleven times in twelve. The twelve houses are counted from the rising sign, so they go with it, and so does the Midheaven, the point overhead. Everything that depends on "which house is this planet in" is therefore off the table.
What doesn’t need it
The planets move slowly enough that a date fixes their signs. The Sun moves about one degree a day and changes sign once a month, so only people born within hours of a cusp need a time for it. Mercury, Venus and Mars change sign every few weeks to months; Jupiter and beyond take a year or more. The aspects between all of them, which carry the tension and talent in a chart, are computed from those positions and are barely affected by the hour.
The Moon is the one to watch. It moves about thirteen degrees a day and changes sign every two and a half days, so on roughly two days in five it crosses a sign boundary at some point during the day. If your birthday is one of those, the Moon sign calculator shows both candidates and the hour the switch happened, and you may recognise yourself in one of them.
How the reading adapts
The chart is computed for noon, and every house-dependent claim is dropped: the reading does not name a rising sign, does not place planets in houses, and reads the love section from Venus and its aspects rather than from the seventh-house cusp. The headline section synthesises Sun and Moon instead of the big three. It is a shorter list of anchors but the same depth on each, and the sections on how you think, where you grow, your edge and the undercurrent are almost unchanged, because they lean on planets and aspects.
How to find your birth time
Start with the long-form birth certificate. In the United States the hospital-issued long form usually records the time; the short "abstract" version does not, and you can request the long form from the vital records office of the state you were born in. In England and Wales birth certificates do not record time except for multiple births; Scotland’s do. Many European countries record it. Beyond documents: hospital records if the hospital still exists, a baby book, and the memory of whoever was in the room, which is usually accurate to the hour and often to the quarter-hour, and an hour is enough for the rising sign most of the time.
What we do not offer is rectification, the practice of guessing a birth time backwards from personality or life events. It is a legitimate specialist skill and not something a form can do honestly.

Questions, answered
Is my Moon sign reliable without a birth time?
On most days yes. The Moon changes sign every two and a half days, so on roughly two days in five it switches at some hour; if your birthday is one of those, the Moon sign calculator shows both signs and the switch time.
Is the reading cheaper without a birth time?
No, it is the same reading at the same price, written to the same brief with fewer anchors. What you lose is the rising sign and house-based content, not the depth on what remains.
Can you work out my rising sign from my personality?
We don’t. That is rectification, a specialist skill that needs a long conversation and dated life events, and a form that claims to do it would be guessing.
Can I add my birth time later?
Yes. Compute the chart again with the time; the chart is free every time. A new reading would be a new purchase, because it is generated fresh from the new positions.
