The five limbs of the day — tithi, nakshatra, yoga, karana and vara — with exact end times, plus every daily muhurta window: Choghadiya, Hora, Rahu Kaal, Yamaganda, Gulika and Abhijit. All windows are anchored to the actual sunrise and sunset at your city.
Amrit, Shubh, Labh and Char choghadiya are auspicious for new beginnings; Rog, Kaal and Udveg are avoided. Rahu Kaal, Yamaganda and Gulika are computed as the classical eighths of the actual daylight — never fixed clock hours. Abhijit muhurta (solar noon ± 1/30 of daylight) is omitted on Wednesdays. Timezone is detected automatically from the selected city.
