New Year's Day, known as 'Año Nuevo' in Spanish, is a significant holiday in Spain. It is celebrated on January 1, marking the start of a new calendar year. This holiday is observed across the country, with both public and private sectors closing for the day. It is a day full of joy and celebration, with many Spanish people spending the day with their families.

The celebrations begin on New Year's Eve, or 'Nochevieja', with people gathering in main squares such as Madrid’s Puerta del Sol to eat the traditional '12 grapes of luck' for the 12 strokes of midnight, each representing good fortune for the coming months. Fireworks and parties abound, carrying on well into the New Year's Day. Many cities and towns also organize New Year's Day parades and other public gatherings.

A unique tradition on New Year's Day in Spain is the 'First Bath of the Year', particularly in the coastal areas. A number of brave individuals start the year with a dip into the cold sea water to shake off the hangovers and bring prosperity for the new year. Whether it's participating in unique traditions, feasting on Spanish delicacies, or spending quality time with loved ones, New Year's Day in Spain is truly a festive and spirited holiday.
