Your exact Sun sign from the Sun's true longitude at birth — not an approximate date table
Offset is auto-filled from the city (Sri Lanka historical changes handled). For other countries, adjust for daylight-saving time if it applied at that date.
Sun 29°42′
Born on the cusp! Only 0.3° from the Gemini boundary
Sun 23°30′
6.5° from the nearest boundary — your sign is unambiguous
The Sun enters each sign at a specific instant that varies by up to two days across years (leap-year drift), so newspaper date ranges misclassify millions of cusp births. Astronomically there is no ambiguity: at your birth moment the Sun had one exact longitude, computed here to arc-minute precision. Note that the sidereal (Vedic) Sun sign is usually one sign behind the tropical one because of the ~24° ayanamsa — both are shown so you can see where each tradition places you.
