The dashed line is the street. Where the sun's curve touches it are the henge days. Drag across the year to move the sun.

This is where the rising or setting sun lines up with Länsituuli in Espoo.

The date above is the next time it happens, computed from the street's geometry. The windows further down list the full range of days the alignment holds.

This entry is a geometry-verified proposal, not an established local tradition. The pin marks the relevant street corridor rather than an exact standing position. Weather, buildings, terrain, and access can affect what is visible.
