There's revelry around the globe on 31 December, but it's north of the border that folk really let their hair down.
More than half a million visitors now attend the four-day Hogmanay celebrations in Edinburgh alone. The first two days of the new year are public holidays in Scotland, giving revellers plenty of time to recover from all the partying.
Hogmanay celebrations in Scotland's capital city kick off at 7pm on 30 December with a free torchlight procession and fireworks display. Proceeds from the sale of torches go to local charities. The word Hogmanay is thought to have originated from 'Hoog min dag', which means 'big love day' in Flemish-Dutch.
On New Year's Eve, West Princes Street Gardens host a concert from 9pm and some truly spectacular midnight fireworks. Lily Allen's the headline act this year, supported by Soul II Soul and Bjorn Again – playing against the stunning backdrop of Edinburgh Castle.
There's also a massive street party on the same night, with live music and entertainment, DJs, giant screens and outdoor bars. Why not join in The Keilidh – an outdoor ceilidh experience set within an exclusive area of the Hogmanay Street Party. A ceilidh (pronounced 'kay-lee') features traditional Scottish music and dancing, along with a Ceilidh Caller to teach you all the moves.
The main Hogmanay celebrations kick off in George Square, where there's an event for 25,000 ticket-holders. Join one of Scotland's biggest outdoor ceilidhs and enjoy entertainment, food, drink and plenty of Scottish music. There are arts and crafts for younger revellers, as well as storytelling and traditional dancing. Around 100,000 people take to Glasgow's streets on New Year's Eve, so the atmosphere is electric. There are also plenty of indoor events from concerts to ceilidhs and dances to DJ nights.
