Why Birth Time Matters
The Ascendant (Lagna) changes every 2 hours. Without birth time, house-based predictions (career, marriage, health by house) lose precision. However, several classical methods still provide useful guidance.
Method 1: Moon Chart (Chandra Kundli)
Use the Moon sign as a reference point instead of the Ascendant. Nakshatra-based gun milan in Ashtakoot matching relies primarily on Moon positions, so marriage matching can proceed with date-only birth details.
Method 2: Approximate Time (12:00 PM Default)
Enter noon as a default time to get a rough chart. Focus on planetary sign placements and nakshatra, which do not change with time of day. Avoid interpreting house-specific predictions from this chart.
Method 3: Name-Based Gun Milan
Ashtakoot matching by name uses the Moon nakshatra derived from the name syllable when birth time is unknown. AstroKaya's kundli milan by name tool supports this workflow.
Method 4: Prashna (Horary) Chart
When birth data is completely unknown, a Prashna chart cast for the moment of the question can answer specific yes/no queries. This requires a skilled astrologer.
