In Vedic Astrology, calculating the Ascendant (Lagna) correctly is extremely important because the entire horoscope depends upon it. The Lagna represents the zodiac sign rising on the eastern horizon at the exact moment of birth.<\/p>\n\n\n\n
For births occurring after sunset and before the next sunrise, astrologers use special methods involving Sunset Time, Dinmaan, Ratrimaan, and Isht Kaal for Night Births.<\/p>\n\n\n\n
What is Night Birth in Astrology?<\/strong><\/p>\n\n\n\n A birth is considered a Night Birth when the birth time occurs: Why Night Birth Calculation is Different<\/strong><\/p>\n\n\n\n During daytime, Isht Kaal is calculated from sunrise. However, for night births, the elapsed time must be calculated differently because the Sun is below the horizon.<\/p>\n\n\n\n Important Terms in Night Birth Calculation<\/strong><\/p>\n\n\n\n Dinmaan<\/strong> Ratrimaan<\/strong> Isht Kaal<\/strong> Traditional Time Units<\/p>\n\n\n\n – 1 Day = 60 Ghati Basic Requirements for Night Lagna Calculation<\/strong><\/p>\n\n\n\n 1.
