Questions
What does the poster actually show?

A smooth curve tracing the hours of daylight for every day of the year in Les Franqueses del Vallès — from the shortest day in winter to the longest in summer and back again. The X axis is the calendar; the Y axis is daylight duration. The chart is framed with the city name, coordinates, and year. An optional occasion marker pins a specific date on the curve.

How accurate is the astronomy for Les Franqueses del Vallès?

Very. Daylight hours are computed using Spencer's (1971) solar declination formula with a −0.833° correction for atmospheric refraction and the sun's semi-diameter — matching the standard used by professional almanacs. The coordinates used are 41.61929, 2.29829.
