No birth time
Many people do not know their exact birth time, but a Vedic chart is still far from useless without it. Your Moon sign, nakshatra, and most planetary positions are readable from your birth date and place alone; only the ascendant (lagna) and the house framework truly need the time. This hub explains what you can and cannot read, and how Stellr handles birth-time uncertainty.
The honest method Stellr uses when your birth time is missing or approximate.
Your Moon sign is usually readable from date and place, even without an exact time.

Most of the chart still works. The Moon sign and nakshatra are stable across much of the day, the nine planets sit in the same signs, and Vimshottari dasha periods (counted from the Moon) can still be read. This already answers many timing and personality questions.
The ascendant (lagna) and the house positions of planets need an accurate time, because the lagna moves about one sign every two hours. When the time is unknown, Vedic astrologers use birth-time rectification — narrowing it from known life events — or read from the Moon as the reference point.
Yes. Without an exact birth time you can still read your Moon sign, nakshatra, the sign positions of all nine planets, and your Vimshottari dasha periods counted from the Moon. Only the ascendant and the house framework need an accurate time.
Moon-based readings — emotional patterns, nakshatra traits, and dasha timing — stay reliable without a birth time. What becomes uncertain is the ascendant and which house each planet falls in, so house-specific predictions are weaker until the time is estimated or rectified.
From date and place alone you can usually determine your Moon sign and nakshatra, the signs of all planets, current and upcoming dasha periods, and major yogas that do not depend on houses. That covers a large share of common questions about timing and temperament.
Birth-time rectification is the method of estimating an unknown birth time by matching the chart against known dated life events — marriage, career changes, relocations — until a time produces a chart consistent with what actually happened. It is how astrologers recover a usable ascendant.
