What is the name of the massive New Year's Eve street celebration held in Edinburgh?

The massive New Year's Eve street celebration held in Edinburgh is Edinburgh's Hogmanay. The multi-day festival centers on December 31 and traditionally features a torchlight procession, concerts, a street party and a midnight fireworks display.

“Hogmanay” is the Scots word for New Year's Eve and also denotes Scotland's wider New Year customs. Edinburgh's modern festival expanded substantially in the late twentieth century, becoming an internationally marketed event with ticketed venues and large outdoor crowds. Programming changes from year to year for safety, weather and civic reasons.

The festival is distinct from Hogmanay traditions elsewhere in Scotland, such as fire festivals and first-footing visits. It is also separate from the Loony Dook, a January 1 swim held in nearby South Queensferry. These events may appear in the same holiday itinerary, but Edinburgh's Hogmanay specifically names the capital's organized celebration.
