Astronomy & the Islamic Calendar

Guest Speaker

Thursday, 30th July 2026 (19:45 - 22:00)

Venue: Hybrid

Discover the fascinating connection between astronomy and timekeeping in this insightful talk, Astronomy & the Islamic Calendar, presented by Engineer Qamar Uddin. The Islamic calendar is deeply rooted in lunar observation, with key dates—such as the start of Ramadan and the celebration of Eid - determined by the sighting of the crescent Moon. In this session, Qamar will explore how astronomical knowledge and modern techniques are used alongside traditional methods to track the lunar cycle and establish important dates across the UK. Drawing on over two decades of experience in engineering and his work coordinating a nationwide network of crescent moon observers, Qamar offers a unique perspective that blends science, culture, and community. Whether you're interested in observational astronomy, calendar systems, or the practical challenges of moon sighting in the UK, this talk provides a compelling look at how astronomy continues to shape everyday life.
