I don't know my birth time. Is that a problem? No. The reading only uses positions that can be calculated for certain. Without a time, it stays careful about what depends on it, like the Moon's exact placement. It's still personal and still worth having.
Why do you ask for my birth place? With your birth time and place, your reading also includes your rising sign and the life areas your planets fall in. Without them, it's based on your birth date and the real sky.
How are the planetary positions calculated? The Linalux Astro Engine rebuilds that moment with the same kind of high-precision ephemeris data astronomers use. The AI calculates nothing and invents nothing. It only puts the result into words for you.
Does every reading come out the same? No. Your birth chart is fixed, but the sky changes every day. Each reading is where your birth moment meets today's real transits.
