https://ejournal.uin-suka.ac.id/ushuluddin/li <p><strong>Aims and Scope<br /></strong><br /><em>Living Islam: The Journal of Islamic Discourses</em> is an interdisciplinary academic journal that explores the <strong>philosophical dimensions of Islam</strong> as a transformative force addressing contemporary challenges and lived realities. The journal provides a platform for <strong>critical and constructive engagement</strong> with Islamic philosophy, bridging theory and practice to contribute to global discussions on ethics, social justice, and human flourishing.</p> <p>The journal focuses on:</p> <ol> <li><strong>Philosophical reflections</strong> on ethical, spiritual, and social dimensions of Islamic living, addressing critical issues such as digital ethics, environmental sustainability, and pluralism.</li> <li><strong>Reinterpretations of classical Islamic thought</strong> in response to global challenges, fostering conceptual innovation within Islamic philosophy.</li> <li><strong>Interdisciplinary approaches</strong> connecting Islamic philosophy with fields such as education, technology, psychology, and public policy to generate actionable insights.</li> <li><strong>Empirical and theoretical studies</strong> analyzing how Islamic philosophical principles shape individual and collective identities in diverse cultural and geographical contexts.</li> </ol> <p><em>Living Islam</em> aspires to redefine the role of Islamic philosophy as a global intellectual force, offering <strong>fresh perspectives on lived Islamic experiences</strong> and bridging <strong>philosophical inquiry with real-world applications</strong>.</p> Universitas Islam Negeri Sunan Kalijaga Yogyakarta en-US Living Islam: Journal of Islamic Discourses 2621-6582 <ul><li>Authors who publish with this journal agree to the following terms: </li><li>Authors retain copyright and grant the journal right of first publication with the work simultaneously licensed under a <a href="https://creativecommons.org/licenses/by-nc-sa/4.0/" target="_blank">Creative Commons Attribution License</a> that allows others to share the work with an acknowledgment of the work's authorship and initial publication in this journal.</li></ul><ul><li>Authors can enter into separate, additional contractual arrangements for the non-exclusive distribution of the journal's published version of the work (e.g., post it to an institutional repository or publish it in a book), with an acknowledgment of its initial publication in this journal.</li></ul><ul><li>Authors are permitted and encouraged to post their work online (e.g., in institutional repositories or on their website) before and during the submission process, as it can lead to productive exchanges, as well as earlier and greater citation of published work.</li></ul> https://ejournal.uin-suka.ac.id/ushuluddin/li/article/view/6535 <p>This study examines whether—and how—a pre-calculated, single, uniform Hijri calendar can be justified from Qur’an and Hadith and operationalized with established astronomical rules. It addresses persistent disunity arising from fragmented practices in a highly interconnected “global village.” A mixed-methods design integrates: (i) a normative–conceptual analysis via Khaled Abou El Fadl’s negotiative method (text–author–reader) to derive scriptural bounds (twelve lunar months without intercalation; calculability; 29/30-day months; hilal as civil mīqāt; semantic range of ra’ā); and (ii) a computational–astronomical evaluation of a two-condition global rule anchored in the International Lunar Date Line (ILDL): S1—global conjunction occurs before local sunset along the IDL (~180°E; ±20° lat), and S2—an imkān al-ru’yah threshold is met on a 60°W test line (±20°; prototype 0.52% illumination). Topocentric ephemerides with standard parallax/refractive corrections (UTC, ΔT) are used, with ~500-year robustness checks and comparisons to regional criteria (e.g., MABIMS). Scriptural analysis legitimizes the use of information/calculation for dating while respecting Sunnah. The two-condition scheme prevents pre-conjunction starts (S1) and ensures expected visibility on the same day (S2). Simulations over ~500 years converge to the lunar synodic mean (~29.53 days) and align with the concept of ḥukmī ru’yah and Istanbul 2016 recommendations. Implementation mapping shows regional variation is historically instrumental; an IDL-anchored global maṭla‘ is operationally coherent. The study unifies a scripturally anchored rationale with ILDL-based imkān into a testable, auditable global rule and a realistic pathway for majority/minority contexts. Adoption of the two-condition rule, supported by a cross-national astronomy–fiqh clearing house and multi-year calendars, can synchronize worship dates and public services. Education systems benefit through stable academic calendars, assessment schedules, and digital platform integration across jurisdictions.</p> Abdul Halim Bin Abdul Aziz Alim Roswantoro Copyright (c) 2025 Abdul Halim Bin Abdul Aziz, Alim Roswantoro http://creativecommons.org/licenses/by-nc-sa/4.0 2025-11-01 2025-11-01 8 1 1 10 10.14421/lijid.v8i1.6535
