We look at all the Round 11 games
The traditional festive season local derbies are set to take centre stage as the Pro12 Round 11 provides an exciting escape from turkey and TV.
The games in Scotland and Wales take place on Boxing Day, whilst Ireland foregoes St Stephens' Day games and sticks to the traditional Friday and Saturday slots.
Local bragging honours between Edinburgh and Glasgow in Scotland are enhanced by the awarding of the 1872 Cup to the aggregate winner over two legs, and Glasgow Warriors will be keen to retain that trophy for a fifth year.
In Wales too the games take on a very local nature in Newport/Cardiff and Llanelli/Swansea avoiding the necessity of a long trip up the M4 motorway.
By the New Year we should know who is best in the east as well as the west of Wales, setting the scene nicely for the 'Judgement Day' double header at the Millennium Stadium in April.
On Friday, table topping Munster welcome Connacht to Thomond Park, when the hosts will be aiming to extend their lead at the top even further, whilst on Saturday the attention turns to Treviso in Italy, the home side not having had a game for two weeks as their Round 10 fixture in Glasgow was called off due to a waterlogged pitch.
The round wraps up Saturday with the repeat of last year's final when champions Leinster welcome Ulster back to the RDS for the first time since their loss there last May. Due to construction work Ravenhill was unavailable for the final but the Ulster fans travelled in their thousands to Dublin to create a 'home away from home' atmosphere, and many will repeat the trip to see if their team can be avenged.
In all it promises to be bumper festive feast of rugby.
We look at all the Round 11 games!

Leinster v Ulster
(RDS Dublin - Kick-off: 18.45; 18.45 GMT)
Leinster have slipped to back to back defeats, against Northampton in the European Cup and Edinburgh in the Pro12.
The Leinstermen's solo defeat at the RDS since the 2012 Pro12 final was 18-22 to Ulster in this equivalent fixture last season (played on 30th March), it represents Leinster's only home defeat to a fellow Irish province since 2008.
Ulster won a fifth successive game in all competitions with their 13-6 home defeat of Zebre on Friday.
Ulster's only loss on the road since September was 9-17 at Scarlets on 2nd November. Ulster have won their last three away games in the regular season against fellow Irish provinces.
Ulster won both regular season encounters against Leinster in the Pro12 last season, but when they met for a third time in the 2013 Final (for which Ulster as top seeds nominated the RDS as their preferred venue) Leinster gained revenge with a 24-18 triumph.
The Ulstermen have won only one of their eight previous visits to the RDS.
Leinster: Leinster: 15 Zane Kirchner, 14 Dave Kearney, 13 Brendan Macken, 12 Noel Reid, 11 Luke Fitzgerald, 10 Jimmy Gopperth, 9 Isaac Boss, 8 Jordi Murphy, 7 Sean O'Brien, 6 Rhys Ruddock, 5 Mike McCarthy, 4 Leo Cullen (captain), 3 Martin Moore, 2 Aaron Dundon, 1 Michael Bent.
