On Monday, February 5, Nutella enthusiasts worldwide unite to celebrate World Nutella Day. Everywhere – on social media, at home and in the office – fans gather to share recipes, stories and enjoy the world's favorite hazelnut spread. The first World Nutella Day was founded by American blogger Sara Rosso on February 5, 2007. She loved Nutella so much it deserved a holiday… and Nutella fans loved it! Soon, World Nutella Day became a global phenomenon thanks to all the fans who shared their love for Nutella by posting photos, recipes, poems and messages on social media.
