Abstract

The Rowot Sasak Calendar is an indigenous calendrical system that once connected ritual time, agricultural cycles, and ecological knowledge in Lombok. This article examines how Islamization and cultural acculturation gradually shifted the calendar from a lunisolar-stellar system to a predominantly lunar-religious system, thereby weakening its agrarian and seasonal functions. The study aims to explain the calendar’s original astronomical structure, analyze the consequences of removing intercalation, and propose a culturally grounded model for restoring its ecological relevance. Using a qualitative-descriptive approach based on ethnoastronomy and religious-cultural studies, the research was conducted in East Lombok, North Lombok, Central Lombok, and West Lombok in 2025. Data were collected through participatory observation, semi-structured interviews with four key informants, analysis of warige manuscripts and local calendrical records, and comparative astronomical calculations. The findings show that the omission of intercalation caused an annual drift of about 10 to 11 days. Reinstating a thirteenth-month mechanism can restore the calendar’s lunisolar logic while preserving its religious, cultural, and social functions.

Abstract

The determination of the Islamic lunar month through ru’yat al-hilāl remains contested in Indonesia, particularly when individual testimony conflicts with established visibility criteria (imkān al-ru’yah). This study examines the concept of ḥadīd al-baṣar in the thought of Ibn Ḥajar al-Haytamī and its implications for moon sighting testimony in Indonesia. Using qualitative library research and Fazlur Rahman’s double movement theory, this study reconstructs the historical background of Ibn Ḥajar’s view and contextualizes it within contemporary practice. The findings show that his concept was shaped by Shāfi’ī legal methodology, early astronomical knowledge, and the absence of optical instruments. Testimony based on ḥadīd al-baṣar cannot serve as a general legal basis but may be personally binding. In Indonesia, such testimony is not institutionally accepted when it contradicts official visibility criteria.
