Picnic is a kind of outdoor dining. It is organized in the open air on a meadow, park, etc. It is part of family trips or events, gatherings, corporate and other meetings. For a picnic, food is served in a picnic basket.

The word picnic (pique-nique) comes from the French language. Allegedly, this type of informal meal outside has become a popular pastime in France after the revolution. In the 18th and 19th centuries the picnic was a social event with luxurious meals and drinks, and their preparation took several days. Picnic also served in political protests where large groups of people gathered. For example, a pan-European picnic was held on August 9, 1989, at the Austro-Hungarian border at Sopron, Hungary. This picnic was part of a revolutionary wave that led to the abolition of the Iron Curtain.

Today you have the chance to celebrate this day by eating outdoors in the open with friends or family.

On June 20, 2009, the world's largest picnic was held in Lisbon, Portugal, where more than 22,000 people attended the picnic, according to the Guinness Book.
