Indonesia is a country of diverse ethnicities, races, cultures, languages and religions framed in a national motto namely Bhinneka Tunggal Ika (Unity in Diversity). However, it is common knowledge that there is tension, if not outright conflict, due to divergent viewpoints and perspectives on events.  to identify the underlying factors that contributed to the disagreement over how to determine the start of the Hijri month and to propose solutions. This study examines the real situation in the area through a qualitative descriptive analysis using Islamic legal and sociological methodologies. The findings of this study indicate that disagreements and tensions within communities over when the Hijri month of 1 Shawwal 1444 H began, which resulted in the arrest of AP H individuals, were caused by a lack of knowledge of the legal foundations relied upon by scholars when rendering judgments or the techniques employed by mass organizations when determining the month's beginning. As a solution to this problem, the government has provided a discourse on religious moderation to encourage tolerance of one another in the face of all current issues. It is advised to follow the Hanyan government's determination of the first day of the month because it allows the people to practice their respective religious beliefs. The general people must understand that Indonesia's diversity and unity are gifts from God and that the difference is a grace that must be kept.
