When and where were you born?

Your rising sign (lagna) changes roughly every two hours, so even a 20-minute difference can shift which sign — and which house every planet falls in — is used for your reading. If you don’t know your birth time, we’ll say so plainly: we compute a solar-noon chart and mark the lagna and house positions as unreliable in the reading itself, rather than guessing and presenting it as fact. Your Moon sign, nakshatra and planetary period (dasha) barely move within a day, so you still get real, specific value.
