The ascendant advances through the whole zodiac every day, changing sign about every two hours (faster or slower depending on latitude and season). A birth time that is off by 30 minutes can move the lagna into the next sign — which is why Sri Lankan horoscopes record the time to the minute. The calculation converts your birth moment to sidereal time, then solves the horizon–ecliptic intersection for your exact latitude and longitude. Sinhala astrology reads the sidereal (නිරායන) result; Western sun-sign columns use the tropical one.
