Freemasons historically celebrate two feasts of saints who are both named John. The feast of John the Baptist falls on 24 June, and that of John the Evangelist on 27 December, roughly marking mid-summer and mid-winter. During the Eighteenth Century, the Premier Grand Lodge of England and the Grand Lodge of Ireland favoured the day of John the Baptist, while the Grand Lodge of Scotland, the Ancient Grand Lodge of England and the Grand Lodge of All England at York installed their Grand Masters on the feast day of John the Evangelist. The United Grand Lodge of England was formed on 27 December 1813.
