National Amber Day is observed on March 28 and celebrates individuals named Amber. The name Amber is derived from the Arabic word ‘ambar,’ meaning ‘jewel,’ and refers to the fossilized tree resin found primarily in the Baltic Sea region. This resin is transformed into the gemstone amber through a process involving heat and pressure. The name Amber gained popularity as a female name in the 19th century and became widely used in the 1950s, likely influenced by the novel "Forever Amber." Customs associated with the day include honoring those named Amber, reflecting on the significance of the name, and appreciating its historical and cultural roots.
