This site is an independent platform created to provide concise and accessible information about the various committees and methodologies used for Hilal (moon) sighting. We are not affiliated with, endorsed by, or representative of any specific group, organization, or school of thought. Our goal is purely informational – to help users understand the different approaches and decisions made by various moon-sighting committees. We do not offer recommendations, issue rulings, or promote any particular method. The choice of which opinion to follow remains entirely with the individual.
