Hampshire Day, also known as Saint Swithun’s Day, is observed in Hampshire, a ceremonial county in South East England, every July 15. This day celebrates the history and culture of Hampshire, coinciding with the feast day of Saint Swithun, the patron saint of Winchester Cathedral. The celebration was inaugurated by Hampshire County Council in 2019 as part of a campaign to honor the heritage of England's historic counties. Activities typically include raising the Hampshire flag, which features a red field with a gold Saxon crown and a gold field with a red and white double Tudor rose. Winchester, once the capital of the Kingdom of Wessex, plays a significant role in this observance, as it houses the cathedral dedicated to Saint Swithun. The day reflects Hampshire's rich history, including its notable figures such as authors Jane Austen and Charles Dickens.
