When and what time of day are street processions organized in most spanish towns?

In most Spanish towns, street processions are typically organized during religious festivals, particularly during Holy Week (Semana Santa) leading up to Easter. These processions usually take place in the evening, often starting around sunset, as the twilight provides a dramatic backdrop for the solemnity of the events. The timing can vary by locality, with some towns holding processions earlier in the day or at different times throughout the week.
