Birth chart by date of birth
No birth time? Enter the date and place: the planets still show, and the chart marks what could change in a day.
Plate 1. Birth details
Example chart: 15 June 1990, London, birth time not known (an invented birth, not a real person)
Plate 2. Chart wheel
No birth time, so a chart cast for noon
Without a birth time the Ascendant, the Midheaven and the houses cannot be known, and they are left out. The planets are shown at noon on the birth date at the birthplace.
Select a planet on the wheel, or a row in a table.

Plate 7. Your chart in plain words
Short readings for each placement, most important first. They state traditional meanings and are not predictions.
Sun in Gemini
Curiosity is often central to how you build a sense of self and find what you want to shine at. You may feel most alive when learning or sharing ideas, but restlessness can make it hard to settle on one focus.
Moon in Pisces
You may absorb the mood around you, with imagination and compassion shaping what feels comforting. Quiet time can help you notice your own needs, though unclear boundaries may make it harder to tell them apart from others’.
Mercury in Gemini
Following a question can lead you quickly to another, as Mercury describes a curious, adaptable way of thinking and sharing information. You may enjoy lively conversations, but keeping your attention on one topic can take effort.
Venus in Taurus
What you value is often expressed through steady affection and a taste for comfort, quality, and familiar pleasures. You may enjoy taking your time, though holding too tightly to what feels secure can limit change.
Mars in Aries
Your drive tends to move quickly from wanting to doing, and Mars is often read as bold, direct action. You may enjoy a clear challenge, yet impatience can make it harder to stay with slower steps.
Jupiter trine Pluto
A drive to grow can work well with a strong instinct for deep change. You may pursue meaning with focus and generosity, though the ease of going all in can make restraint take extra effort.
Moon trine Pluto
Your feelings can work well with a strong instinct for change, power and what runs deep. You may handle emotional turning points with focus, though the ease of going deep can make lighter needs easier to miss.
Moon sextile Neptune
Your feelings can sit easily with imagination, compassion and intuition. You may be sensitive to the mood around you, but blurred boundaries can make it harder to tell your own needs from someone else's.
Yes, your birth date can show your Sun sign and usually the signs of most planets. The Moon may change signs during that date. Without a birth time, the chart cannot reliably show your Ascendant or houses. This calculator uses local noon as an assumption, so treat time-sensitive placements as uncertain until you find the birth time.
What the date can show
The Sun moves slowly, about 1 degree a day, so its sign is usually clear from the date. Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto and the north node also tend to stay in one sign throughout a day. The calculator marks placements that hold all day, so you can distinguish those from placements that may depend on the birth time.
Astrology treats these placements as symbols for reflection. A date-only chart can offer a useful starting point, but it does not describe every part of a chart with equal certainty. The place of birth still matters for calculating the chart, and a time is needed for the angles and houses.
The Moon needs closer attention
The Moon moves about 13 degrees a day and spends about two and a half days in each sign. It can cross from one sign to the next within your birth date, so the date alone may not settle its sign. The calculator shows whether the Moon holds its sign all day or could change during the day.
If it could change signs, the noon chart gives one position based on the assumed time, not a confirmed Moon sign for your birth moment. The Moon's sign is associated with emotional habits and responses in astrology, but read a date-only result with care when the placement is marked as time-sensitive.
What a birth time adds
The Ascendant and houses depend on the exact time and place of birth. The Ascendant can move by about 1 degree every 4 minutes on average, so even a modest time difference may change its degree or sign. Houses divide the chart into areas of life, and their positions also rely on the birth time.
Without the time, these parts cannot be placed reliably. The calculator therefore leaves out the Ascendant and houses in date-only mode. A noon chart is an assumption used to calculate a moment for the date. It is not evidence that you were born at noon, and time-sensitive placements should not be treated as certain.
Finding your birth time
Check your birth certificate first. If it does not list a time, hospital records may help. You can also ask family members whether they remember or kept a note. If you find a time, enter it with your birth date and place to get a chart calculated for that moment.
If no reliable time turns up, the date-only chart can still show placements that hold all day. Keep the Moon uncertain if it could change signs, and leave the Ascendant and houses out of your reading. In astrology, those chart features are symbolic interpretations, not proof or predictions about your life.
Questions
Can I use a birth chart calculator without knowing my birth time?
Yes. Enter your date and birth place, and use the date-only mode. It sets the chart for local noon, so the noon time is an assumption. You can still read the Sun sign and placements that hold all day, while leaving out the Ascendant and houses.
Will my Sun sign change if I enter a different birth time?
Usually not, because the Sun moves about 1 degree a day. If your birth date is near a sign change, however, the exact time can matter. A date-only chart may not settle the Sun sign in that case, so treat the result as uncertain until you find the time.
Can the Moon be in a different sign on my birthday?
Yes. The Moon moves about 13 degrees a day and can cross into another sign within a day. If the calculator marks it as able to change, noon may not match the Moon's position at your birth. The birth time is needed to confirm its sign.
Where can I check for the exact time I was born?
Look at your birth certificate, then check whether the hospital kept records. Family members may also remember the time or have written it down. If you cannot confirm it, use the date-only chart with care: the Moon may be uncertain, and the Ascendant and houses are unavailable.
