What Birth Details Are Required for an Accurate Janam Kundli?

A Janam Kundli is not an arbitrary forecast; it is a precise mathematical and astronomical map of the solar system as viewed from your exact geographic coordinates at the exact second you drew your first breath. ### The Three Sacred Pillars of Birth Details To construct an accurate horoscope, an astrologer requires: 1. **Date of Birth (DD/MM/YYYY):** Determines the positions of slow-moving planets like Saturn, Jupiter, and Rahu/Ketu. 2. **Exact Time of Birth (Hours, Minutes, AM/PM):** - The Earth rotates 360 degrees in 24 hours, meaning the eastern horizon (the Ascendant or Lagna) changes signs roughly every **two hours**. - In subtle divisional charts like the Navamsha (D9) or Dashamsha (D10), a change of just **4 to 8 minutes** shifts the entire astrological interpretation. 3. **Exact Place of Birth (City/Town & State):** - Vedic astrology calculates local sidereal time (LST) and sunrise coordinates based on latitude and longitude. - For example, sunrise in Kolkata occurs nearly an hour earlier than in Mumbai; hence identical clock times produce completely different ascendants. ### What If Your Exact Birth Time Is Unknown? If you were born without an accurate hospital record or if there is a window of uncertainty (e.g. "between 3:15 PM and 3:30 PM"), professional birth-time rectification (Nashta Jataka / Kunda method) can be employed. By cross-referencing landmark past events (education completion, marriage date, sibling births, career shifts), Astro Shivanii pinpoints the correct rising degree.
