First, opening paragraph: set the scene, mention that the total lunar eclipse often called Eclipse 13 De Marzo 2025 in Spanish-speaking regions is a highly anticipated celestial event, explain the date discrepancy first because it falls overnight March 13-14, 2025, so the 13th is the date for observers in the Americas, which matches the context about parts of the Americas getting the total lunar eclipse.
