Cultural Tip
In Spain and most Latin American countries, the meteorological autumn is considered to start on September 1, which aligns with the school year and many cultural festivals (e.g., Día de la Hispanidad). In the Southern Hemisphere, however, September marks the beginning of spring, so the same phrase would be used in a completely different seasonal context.
