Design Development and Analysis of Lunar Crescent Visibility Criterion With Python Introduction: The lunar crescent visibility criterion is a fundamental concept in Islamic astronomy that has been studied extensively in recent years. However, there is a lack of comprehensive research on the development and analysis of this criterion using Python programming language. This book aims to fill this gap by providing a detailed overview of the design development and analysis of the lunar crescent visibility criterion using Python. The book is divided into three main sections: the first section provides an introduction to the lunar crescent visibility criterion and its significance in Islamic astronomy; the second section presents the design development of the lunar crescent visibility criterion using Python; and the third section discusses the analysis and results of the criterion. Section 1: Introduction to Lunar Crescent Visibility Criterion and Its Significance in Islamic Astronomy The lunar crescent visibility criterion is a crucial aspect of Islamic astronomy that determines the visibility of the lunar crescent after the new moon. The criterion is based on the physical properties of the moon and the observer's location on Earth. The visibility of the lunar crescent is essential for determining the beginning of the Islamic month, which is critical for religious and social purposes. The accuracy of the lunar crescent visibility criterion has been a subject of debate among scholars and astronomers for centuries.
