We've taken a look at the last seven seasons' final league table to see if being top on Christmas Day has any bearing on a team's title hopes.
The O's will take comfort from the last four Champions who were all top on December 25.
2017/18 - Christmas Day Leaders: Macclesfield Town / Champions: Macclesfield Town
The Silkmen pulled off one of the biggest shocks seen in recent years in the National League when they finished the season top of the pile. John Askey's men were in pole position on the big day after drawing 1-1 at Bromley to maintain their fine season.
2017/18 - Christmas Day Leaders: Lincoln City / Champions: Lincoln City
The Imps did their title hopes no harm as they beat their closest challengers Tranmere Rovers 2-1 at Sincil Bank to extend their lead to five points.
Under the Cowley brothers, City went from strength-to-strength - finishing the season with a four point cushion at the summit.

2014/15 - Christmas Day Leaders: Barnet / Champions: Barnet
Barnet sat at the summit on Christmas Day of 2015 after their convincing 3-0 win over Chester at The Hive, leading the way with a seven point cushion.
John Akinde's impressive 31-goal haul meant the Bees finished the season just a single point ahead of Bristol Rovers.
2013/14 - Christmas Day Leaders: Cambridge United / Champions: Luton Town
It was a two-horse race for most of the season in truth but Cambridge United sat in first-place on Christmas Day of 2013 with a game in hand over the Hatters.
But Luton weren't finished yet and staged a remarkable turnaround after the turn of the year, eventually finishing 19 points clear to claim the title of Champions.
2012/13 - Christmas Day Leaders: Newport County / Champions: Mansfield Town
Newport led the way on Christmas Day in 2012 with eventual winners Mansfield Town four-points off the summit.
The Stags fought back in the second-half of the season to take the title. Newport recovered however, eventually gaining promotion in the play-offs.
2011/12 - Christmas Day Leaders: Wrexham / Champions: Fleetwood Town
Wrexham led the way through the festivities in 2011 but only on goal difference. The Welsh side fell away however and eventually lost to Luton Town in the play-offs.
Fleetwood Town claimed the title, finishing five points ahead of the Red Dragons with a little help from a certain Jamie Vardy.
