The average British family will have their first alcoholic drink on Christmas Day at 9.05am, new research has revealed.
Loved ones will fall out at least five times on the big day, with rows sparked by stressed hosts, relatives getting in the way and a lack of space.
Hotel chain Travelodge quizzed 2, 500 Brits about their December 25 schedules for the study of a modern day Christmas.
Grown ups start the day with a drink at 9.05am, followed by breakfast at 9.19am.
And within half an hour, families are bickering about mess from presents and timings of their festive celebrations (overall average time per family).
The top cause of bust-ups comes from organising the perfect day and getting people to contribute (55 per cent), figures show.
Nearly half of us households experience strife fuelled by kids not being impressed with their gifts (47 per cent) or guests getting in the way of mum’s cooking (43 per cent).
Next up are family members having too many pre-dinner drinks (35 per cent) and an old family argument that resurfaces (29 per cent).
A quarter of households have rows caused by mums stressing about an under or overcooked turkey (24 per cent), according to the survey.
Typically, it’s mother-in-laws who prove the most argumentative people to have around on Christmas Day (22 per cent).
But father-in-laws (15 per cent), cousins, sisters and mothers (14, 12, and 11 per cent) aren’t far behind in the irritating stakes.
Corinne Sweet, Relationship Psychologist, said: “It’s not only the turkey that gets overheated at Christmas.
“Family flare-ups are inevitable, especially as people who seldom see each other are suddenly thrown together 24/7.
“It’s essential to prepare yourself psychologically by lowering your expectations as Christmas can’t be perfect and it’s essential to take time-out every time you feel riled.
“Having a nap or even a lie-in can work wonders, as people are especially niggly on not much sleep.
“Make space for yourself this Christmas, even a walk round the block can help.
“Set boundaries with relatives and kids, and create some quiet ‘me-time’ to reflect on what the spirit of Christmas is really all about.”
One in seven Brits will go to Midnight Mass (15 per cent) and similar numbers will watch the Queen’s speech (15 per cent) this year.
Last year 25 per cent of the nation tuned in for Her Majesty’s address.
Travelodge spokeswoman Shakila Ahmed said: “The study revealed Christmas dinner is eaten later than ever.
