龍躍八字 - 八字排盤命理工具

Longyue Bazi is a professional Bazi (Four Pillars of Destiny) chart generation tool designed for Bazi practitioners and researchers. All calculations are performed offline on the device, requiring no account, no server connection, and no data collection.

【Free Switching of Base Lines: Heavenly Stems and Hidden Stems Available】 Most chart generation programs only use the Day Stem as the base line. With Longyue Bazi, a single click on the pillar head allows you to switch to the Year Stem, Month Stem, or Hour Stem as the base line. v3.0 goes further; clicking on any hidden stem in the original chart allows you to use that hidden stem as the base line. The original chart, major luck cycles, annual luck cycles, monthly luck cycles, and daily luck cycles, along with the printed chart, are all recalculated instantly. Selected hidden stems are marked with the character "体" (body). Using hidden stems as the base line is quite rare among similar tools, making it suitable for studying family relationships, palaces, and interpersonal relationships. Clicking on the Day Pillar again will revert the settings.

【True Solar Time Correction】 Built-in longitude data for 27 cities automatically converts clock time to true solar time during chart generation. After selecting your birthplace and date, the program will automatically check whether daylight saving time or standard time is observed in that location that year and provide a prompt—if your watch time is affected by daylight saving time, the hour pillar will be calculated incorrectly, and this correction is designed for this purpose.

【Unlimited Scrolling of the Four Layers of Flowing Fortune】 The four layers—Major Luck, Annual Luck, Monthly Luck, and Daily Luck—can all be freely scrolled left and right, without being limited to ten or twelve grids. Selecting any grid will automatically align the upper layer—selecting a monthly luck from another year will jump the annual luck accordingly; entering a different major luck cycle will also jump the major luck cycle. The hidden stems within the flowing fortune grid can be displayed as hidden stems, ten gods, or both.

【Four Birth Time Input Methods】
• Rotating Menu: Five columns for year, month, day, and hour, each labeled with the Heavenly Stem and Earthly Branch. The Four Pillars are displayed instantly at the top.
• Manual Input: Five-column 24-hour format, automatically jumping to the next column after entering the required number of columns.
• Lunar Calendar Input: Directly select the lunar year, month, and day (including leap months), instantly displaying the corresponding Gregorian calendar date.
• Heavenly Stem and Earthly Branch Selection Chart: Select step-by-step from year → month → day → hour. Hours are divided into thirteen columns (early Zi, Chou to Hai, late Zi).

【A4 Destiny Book Printing】
Uses Android's native printing function, with options for a printer or saving as PDF. The layout includes the Four Pillars, Hidden Stems, Ten Gods, Major Luck Periods table, basic data on the Five Elements and Heavenly Stems and Earthly Branches, and a 100-year annual fortune chart.

【Records and Notes】
The destiny chart can be saved, searched, and filtered by Day Master or Month Pillar. It can be divided into folders and pinned to the top. Each destiny chart can have notes added, recording the client's description or clues to the chart determination. Notes will be exported along with the records but will not be printed on the destiny book.

【Comparison of Two Charts】 You can view two charts simultaneously. On mobile phones, the charts are arranged vertically (top to bottom); on tablets, they are arranged horizontally (side to side). A single tap on the year at the top will jump to both charts for that year, allowing you to easily see the different fortunes of each person within that year.
