I know absolutely nothing about motor sports. As part of my job I need the dates of all the Grand Prix races worldwide. I've got dates on the official F1 website but don't know if they're all Grand Prix races or if they include some others - for example are the Formula 1 Gran Premio de Espana and the Formula 1 Grosser Preis Santander von Deutschland actually Grand Prix? Or are they other F1 races?
Your expertise would be appreciated!
