A new study says that the happiest time on Christmas Day for most people is early afternoon, at 1:55 pm.
It emerged that people are completely happy only after presents have been opened, dinner has been cooked and served, and the children are busy with their toys.
Despite the initial stress, over half of those polled say Christmas Day is their favorite holiday and a third say it's the happiest day of the year.
"A lot of thought and effort goes into each and every Christmas, and people work hard to make it special and create memories that will last a lifetime," the Telegraph quoted a spokesman for Three Barrels Brandy as saying.
"Christmas morning tends to be a rush in most households - mums are struggling with the dinner, children are unwrapping presents, and dads are finding batteries to go in the toys.
"It's important to try and enjoy those more hectic moments as well, as these often make the funniest Christmas memories and will be told at Christmas' for years to come," he added.
Three quarters of those polled claimed the Christmas dinner is largely responsible for any stress endured on the morning of the 25th.
Once dinner is on the table, 56 per cent of people reach their happiest point of the day.
"It's sometimes easy to get carried away with the planning and worry that comes with arranging Christmas, and before you know it it's been and gone," the spokesman said.
"On Christmas Day, most adults are more concerned about creating a happy day for everyone else, but it is important that people can enjoy the holiday for themselves as well," he added.
