Avenida de Mayo: Buenos Aires

The dates below show when the rising or setting sun lines up with Avenida de Mayo in Buenos Aires, computed geometrically with the same engine as the interactive map. This is a geometry-based candidate rather than a named local tradition.

This entry is a geometry-verified proposal, not an established local tradition. The street axis checks out mathematically, but the horizon, obstructions, and the best public observation point have not been field-checked.

Streethenge calculates geometric solar and lunar alignments. Visibility on site depends on weather, buildings, trees, terrain, safety, and access.
