The Mayan and Other Ancient Calendars
Author: Geoff StrayPublisher: Bloomsbury Publishing USA
ISBN: 0802716342
Category : History
Languages : en
Pages : 68
Book Description
The only small, popular book on the important subject of ancient calendars. The study of heavenly cycles is common to most ancient cultures. The ancient Egyptians, Chinese, and Babylonians all tried to make sense of the year. But it fell to the later Mesoamerican Maya to create a series of calendars that could be cross referenced. In doing so, the Maya discovered many strange numerical harmonics. Their lunar calendar was extremely accurate-far more so than the Greek Metonic cycle; they tracked Venus to an accuracy of less than a day in five hundred years and their tables could have been used to predict eclipses seven hundred years in the future. This book will provide a much needed compact guide to the Mayan calendar systems as well as covering the essentials of calendar development throughout the world.

Towards an Islamic Lunisolar Calendar
Author: Hisham AbadPublisher: Hisham Abad
ISBN:
Category : Social Science
Languages : en
Pages : 362
Book Description
The Calendar was invented in ancient times to allow nations to pace their economic and social activities with climatic seasons. Throughout the history of civilizations, much depended on organizing and administering an accurate calendar. Hunter-gatherers needed the calendar to predict the migrations of herds of wild animals. As humanity advanced, farming communities required calendars to predict the coming of rain or the time of the flooding of rivers. Traders and seafaring communities needed to map the best time of the year to tackle the dangers of seas when sailing far from home. In contemporary times of globalization, calendars have become even more critical in optimizing the complex supply chains of local and global production cycles. Oral traditions ascertain that the Arabs of the Arabian Peninsula used a rudimentary lunisolar calendar, called in the literature the “Arabian Calendar.” Like with all nations, the lunisolar Arabian Calendar helped the Arabs organize their meager resources in the best ways possible. For example, research showed that the Ḥajj season and its pan-Arabian markets were scheduled to coincide with the date harvesting season peaking from July to September. The abundance of the date harvest available in this period, along with assigning the concept of inviolability to the Arabian months spanning this season, allowed them to travel across Arabia to Mecca to trade in the pan-Arabian markets and to participate in the religious rituals of their pilgrimage (the Ḥajj). It is asserted in this book that Prophet Muḥammad followed the lunisolar Arabian Calendar all his life. At the end of the tenth year after he migrated from Mecca to Medīna, and during his Farewell Pilgrimage, the Qurʾān sternly abolished the process of intercalation, i.e., the Nasīʾ, the very process which allowed the Arabs to organize their various economic and religious activities. When Caliph ʿUmar ibn al-Khaṭṭāb initiated the Hijri Calendar seven years after Prophet Muḥammad death, i.e., in 17 AH, he founded it as “purely lunar,” which meant its months were allowed to float within the solar year. Caliph ʿUmar is famous for his zeal in protecting the fundamental Islamic principle of monotheism. This, I show, was the reason for introducing the Hijri Calendar as purely lunar, because “Nasīʾ,” i.e., Quraysh’s method of intercalation was hopelessly entangled with the polytheistic religion of Quraysh, the Prophet’s tribe, and the guardian of the holy places in Mecca and its environs. The harmful effects of following the purely lunar Hijri Calendar were realized from early on. But the prohibition of Nasīʾ inhibited the early Islamic caliphs from reforming the Hijri Calendar. This book explores the history of the Arabian Calendar and its intimate connection with the Hijri Calendar. The main findings of this book are as follows: 1- The main Ḥajj shrines in Macca are aligned in the direction of sunrises and sunsets of the Summer Solstice day. 2- Quraysh intercalated its Arabian Calendar by forcing the Summer Solstice (SS) Day to occur within the 11th month of the Arabian Calendar, Shawwāl. The Nasīʾ month was added when the onset of the SS was about to transfer to into the 11th month Dhū’l Qaʿda. 3- The onset of the SS day was determined through the sunset alignment along the line joining the posts of “al-Wosṭā and al-ʿAqaba Jamarāt, and also by observing the sun rising from behind the peak of mount Thabīr from the location of the sacrificial altar of pre-Islamic Mina. 4- The Prophet arrived in his migration from Mecca to Medīna on the Days of ʿĀshūrāʾ which corresponded to the dates of 8th of Rabīʿ-I, the 10th of the Hebrew month Tishri, and to the 23rd of September 632. 5- The epoch of the Hijri Calendar must be adjusted back by two days from the epoch used so far. 6- The Farewell Pilgrimage occurred in autumn on September 4, 632 CE, not in spring on March 11, 632 CE.
