Features: This book is a fast calculation method designed for researchers of history, archaeology, and chronology to determine the solar and lunar eclipses over four thousand years before and after the Common Era. It includes methods for calculating the day of the week or the Heavenly Stems and Earthly Branches from the Gregorian and Islamic calendars, converting between the Gregorian, Islamic, and standard Chinese calendars, determining the times of the 24 solar terms, the times of the new and full moons, and the visibility, magnitude, and timings of all lunar eclipses. It also covers the visibility, magnitude, and timings of all solar eclipses. This book enables general historians and archaeologists who are not familiar with astronomy to independently calculate the solar and lunar eclipses over thousands of years using simple arithmetic operations and proportional interpolation. Although the results are approximate, they are sufficient for archaeological and chronological purposes and can also be referenced by general astronomy enthusiasts.
