Christmas in Ireland is the largest celebration of the year although 8 December is traditionally viewed as the start of Christmas with many putting up their decorations and Christmas trees, along with doing their Christmas shopping. Irish Christmas traditions are similar to those in most Western countries.
The greeting for "Happy Christmas" in Irish is Nollaig Shona Duit (Irish pronunciation: [nˠɔlˠɡˠ hɔnˠə dˠɪtʲ]) (singular) or Nollaig Shona Daoibh [plural] (Irish pronunciation: [nˠɔlˠɡˠ hɔnˠə dˠiːv]). The literal translation of this is "Happy Christmas to you". If "Nollaig, Shona, Duit/Daoibh" was literally translated, word for word, into English, it would be "Christmas, happy, to you". The British English expression "Happy Christmas" is more common in Ireland than its American English equivalent of "Merry Christmas".
Ireland is a predominantly Christian country and Christmas plays an important role in religious aspects of Irish life. There are large attendances at religious services for Christmas Day and Christmas Eve, with Midnight Mass a popular choice for Roman Catholics. It is also a time for remembering the dead in Ireland with prayers being offered for deceased at Mass. It is traditional to decorate graves at Christmas with a wreath made of holly and ivy.
In many homes in Ireland the traditional crib, along with the Christmas tree are part of a family's decorations. Family and friends also give each other gifts at Christmas. Some people light candles to signify symbolic hospitality for Mary and Joseph. The candle was a way of saying there was room for Jesus's parents in these homes, even if there was none in Bethlehem.
Irish people spend more and more money each year on celebrating Christmas. In 2006, the total amount spent in Ireland to celebrate Christmas was €16 billion, which averages at approximately €4,000 for every single person in the country. From a survey it was found that 44% will have sufficient money in their monthly income to pay for Christmas. 23% are likely to dip into their savings, while almost half of those surveyed (45%) will have to borrow money to cope. The last 33% of all the people are unknown off their shopping spend. 
In recent years Christmas decorations have appeared in shops in late October side by side with Halloween decorations. In 2009, Christmas radio adverts began in the last week in August. The big traditional Christmas shopping day used to be December the 8th, when many schools would close for the Catholic Feast of the Immaculate Conception and people from rural areas would head to the towns and cities to do their Christmas shopping. With the advent of online shopping and other popular shopping days such as Black Friday, the 8th is no longer a very busy shopping day.
Christmas trees officially go up on 8 December because according to Christian tradition the immaculate conception was on this date. Trees in towns and cities are erected in central locations every year along with lights.
Almost the entire workforce is finished by lunchtime on Christmas Eve or often a few days beforehand. Christmas Day and St. Stephen's Day (Boxing Day in Northern Ireland) are public holidays and many people do not return to work until the next week day after New Year's Day. Many multinational companies and businesses close the day before Christmas Eve and re-open the day after New Year's Day. Shop and public service workers usually return to work the day after St. Stephen's Day and sometimes on St. Stephen's Day if the Christmas sales have started.
During Christmas many weekly or local newspapers are moved and when Christmas Day is falling on Sunday, Sunday Newspapers are moved to Saturday or Christmas Eve.
The Late Late Toy Show is an annual edition of The Late Late Show aired on RTÉ One usually on the last Friday of November and is dedicated to the showcasing of that year's most popular toys. It is regularly the most watched television programme of the year by Irish audiences, and is broadcast live, meaning anything can and has happened. The show, which consists of an adult-only studio audience dressed in traditional Christmas attire, does not accept advertisements which promote toys for its commercial breaks but, whilst new gadget-type toys regularly break down during the live show, being featured on the programme itself has been said to have a major boost to sales of a product over the following number of weeks in the build-up to the Christmas period. The attire of the presenter, namely a jumper, is also subject to speculation in the media beforehand and afterhand. Advertising in 2009 cost €17,000 for each 30-second slot—this compares to €9,750 for the 2010 UEFA Champions League Final.

The Irish number one single for Christmas is announced on Christmas Eve every year.
Santa Claus, Daidí na Nollag (lit. Daddy of Christmas) in Irish and traditionally "Father of Christmas" in Irish English, is known in Ireland as Santy or Santa. He brings presents to children in Ireland, which are opened on Christmas morning. It is traditional to leave a mince pie and a bottle or a glass of Guinness along with a carrot for Rudolph, although in recent years Guinness has been replaced with milk and mince pies with cookies due to Americanisation. Most big shopping centres and malls have a Santa's grotto setup from late November so that shoppers and visitors with kids can visit Santa and tell him what they want for Christmas.
The placing of a lighted candle in the window of a house on Christmas Eve is still practised. Its primary purpose is to welcome Mary and Joseph.
It is traditional to swim in the sea on Christmas morning. This is often done in aid of charity. The 40 Foot in Sandycove in Dublin is a traditional venue for this where hundreds brave the cold temperatures and jump into the sea.
The traditional Christmas dinner consists of turkey or goose and ham with a selection of vegetables and roast potatoes.They also have round cake full of caraway seeds. In Cork and some surrounding areas, Spiced beef is traditionally eaten as part of the Christmas dinner.

On Christmas Eve fish is traditionally eaten as a form of fasting before Christmas.
Christmas celebrations in Ireland are finished on the 6th of January, variously known as Women's Christmas (Nollaig na mBan), Little Christmas or Epiphany, with people taking down their Christmas decorations.
