It's the most wonderful time of the year – and is even more wonderful for any artist who manages to end up top of the tree when it comes to the Official Singles Chart at Christmas.
Celebrating a UK Christmas Number 1 is a festive tradition going back decades. The very first one came back in 1952, when Al Martino claimed the snow-capped summit with Here in my Heart.
Since then, a wide variety of tracks have scored that special Number 1 – from festive faves and beautiful ballads, to dance bangers and, of course, a few whackier tracks that could, in all honesty, only reach Number 1 at Christmas.
Friday 20 December is the date to get in your calendar: that's when the full Christmas Top 40 is counted down on BBC Radio 1's Official Chart, from 4pm. Look back at every Official Christmas Number 1 ever.
The full, extra festive Top 100 and Official Christmas Number 1 will also be available on OfficialCharts.com from 5:45pm.
Last year the Official Christmas Number 1 went to YouTube sensation and dad blogger LadBaby – real name Mark Hoyle – who, along with his wife Roxanne and two young sons, released a new version of Starship’s 1985 hit as an ode to sausage rolls (rather than rock and roll). Proceeds from the single went to food-bank charity The Trussell Trust.
It's a tad early to talk contenders just yet, bu anyone who wants to be in with a shot at landing the Official Christmas Number 1 Award in their stocking must make sure their single is available during the week before the cut-off point for sales and streams to be counted toward the chart, which in 2019 is midnight on December 19.
