The 2026 Lunar New Year falls on Tuesday, February 17. In this updated activity, students will explore the unique naming system of the Lunar New Year, which combines the Heavenly Stems and Earthly Branches. Without explicitly introducing the term "Least Common Multiple (LCM)," they will calculate when the naming pattern repeats and see the connections between math and culture.
