The research surveyed 2,000 British households to see how Christmas Day will be celebrated.
The study found that after the early confrontation, the next family row will take place at 12.42 pm when 38 per cent of children will moan about receiving the wrong presents.
Nearly half of Brits - 45 per cent - admitted that parents will fall out in between 1 pm and 3 pm - because the father has had too much to drink and the mother is stressed about food preparation, The Telegraph reported.
The study carried out by hotel chain Travelodge also showed that the traditional Christmas dinner will be served at 2.23 pm, an hour before the next family feud.
One in ten people revealed that the lunch-time squabble will be about family gossip, 'who is the better person' and old family arguments.
A day consisting of food and drink will result in an evening of bickering at 6.05 pm - when 15 per cent of families will fight for the remote control.
This will be followed by an outburst at 7.25 pm by seven per cent of senior family members trying to play charades.
At 10.15 pm, after the liqueurs have been drunk and the last mince pie has been eaten, tempers will flare up just before bedtime.
"It's not only the turkey that gets overheated at Christmas, family flare-ups are inevitable. This is because people who rarely see each other are suddenly thrown together for the whole day," Corinne Sweet, Relationship Psychologist, said.
"But the most important thing on Christmas Day is to relax and have fun. Make your expectations realistic and appreciate the time spent with your family," Sweet said.
