Lunar conversion and solar-term instants are computed locally using lunar-typescript 1.8.6. Conversion dates and solar-term dates for 2025 and 2026 have been compared against the Hong Kong Observatory. Solar-term times are calculated, displayed to the minute and may differ slightly from published ephemerides; this tool is for cultural learning, not precision astronomical observations.
Today follows your browser’s timezone and updates at your local midnight. Solar-term times use that same timezone, including daylight saving time. Picked dates use local noon for their solar-term context. Lunar dates and lunar festivals follow the traditional Chinese calendar conversion of the displayed Gregorian date; they do not redefine lunar months for your location. Gregorian New Year, Lunar New Year and Li Chun are separate boundaries. No auspicious-day ratings, activity prescriptions or predictions are supplied.
