Edinburgh's Christmas season launches on the second last Sunday of November, with the first in a series of Christmas light nights.
The Voice competitor Saskia Eng, who attended the Edinburgh School of Music from age 11, will turn on the Christmas lights in 2018.
The festive entertainment typically includes choirs from across Edinburgh such as Little Voices Big Stars, Edinburgh Ballet and Edinburgh Rock Choir performing on two stages on George Street in front of an expected audience of around 20,000 people.
Forth One DJ Arlene Stuart will host Light Night 2018.
The Christmas Tree on The Mound, a traditional gift given each year by the people of Hordaland, Norway, to the City of Edinburgh Council, will also be switched on as part of Edinburgh's Night Light celebrations.
Following the switch on of the lights - usually attended by the Lord Provost of the City of Edinburgh and Deputy Convener of Hordaland County Council, there is a firework display at 5pm.
Light Night also marks the opening of many other Edinburgh's Christmas attractions. There is a Christmas market, whisky bar serving cocktails and hot toddies on The Mound, and various fairground rides such as a Big Wheel and 60 metre-high Star Flyer, in Princes Street Gardens. For younger kids, there's two carousels, Christmas tree maze, and other Santa Land activities.
The pop-up ice rink in St Andrew Square is also open for skating (actually opens a day before Light Night). There are a number of smaller Christmas Light Nights in other Edinburgh areas in the days following the main city centre Light Night event.
Edinburgh's Christmas Light Night is a free, public event.
