Eastern Lunar Calendar

The Perpetual Calendar (also known as the Ten Thousand Year Calendar or Almanac) is a complex timekeeping system used in East Asian cultures. It harmonizes the Solar calendar (Earth's movement around the Sun) with the Lunar calendar (Moon's movement around the Earth), while incorporating Eastern philosophies such as Heavenly Stems, Earthly Branches, the Five Elements (Wu Xing), and the 28 Mansions.

Historically, the calendar was designed to bring "peace in ten thousand things". By consulting it, you can identify the energy of a specific day (Auspicious or Inauspicious) and plan important life events accordingly for maximum success.

Beyond simple timekeeping, the almanac serves as a powerful assistant in daily life:

• Selecting Auspicious Dates: Choose lucky days for major events such as building a house, weddings, grand openings, travel, or buying a vehicle, while avoiding inauspicious days.
• Auspicious Hours: Every day, regardless of whether it's generally good or bad, contains 6 Auspicious Hours and 6 Inauspicious Hours. Starting an endeavor during an Auspicious Hour ensures smoother progress.
• Lunar Birthday Conversion: Convert your Gregorian birthday to the Lunar calendar to accurately cast your Purple Star Astrology (Zi Wei Dou Shu) or Bazi (Four Pillars) birth chart.
• 24 Solar Terms: Track the 24 solar terms throughout the year to plan agricultural activities or prepare for seasonal changes that affect health.
