The poll of 2,000 UK households was taken to see how December 25 was celebrated throughout the country.
A second family row is said to take place at 12.42pm, with most family members complaining about the wrong presents, according to the study carried out by Travelodge.
45% of British people surveyed stated that parents have a falling out between approximately 1pm and 3pm, either because the father has drank too much or the mother is getting stressed over the food.
The study showed that dinner is usually served at 2.23pm, while the third row takes place an hour later.

Another row erupts on average at 7.25pm, with grandparents attempting to start a game of charades.
Arguments are also said to occur at approximately 10.15pm before bedtime.
Relationship psychologist Corinne Sweet said of the results: "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. 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."
