While Christmas is quite an event for the British Royal family, the holiday season also brings an unbreakable set of rules and traditions.

It was recently reported that King Charles did not invite Prince Harry and Meghan Markle to Sandringham for Christmas. But Kate Middleton's Christmas concert is going ahead, and for many young children in the royal family, the festive season is reportedly very chaotic. And when it comes to celebrating Christmas in a royal way, there are a few things to do and not do on holiday.

Former BBC Royal Correspondent Jenny Bond recently spoke to the Sun's amazing magazine about how the Royal family celebrates Christmas. "I can't imagine the royal family spreading to the settees wearing slippers and slouch pants, luring booze and chocolate like the rest of us," Bond told the outlet. "A certain degree of politeness is still needed."

Here we summarize some of the alleged rules and traditions of the Royal family during the holiday season.

According to Bond, it is absolutely essential to ensure that guests are not late for the Royal Christmas celebration at Sandringham. But early may be just as bad.

"When you feel like it, you don't just show up at Sandringham," Bond told the outlet. "Guests must arrive at the time they are expected, not before and after."

The Royal family may be immeasurably rich, but that doesn't mean they are expecting expensive gifts for Christmas. According to Bond, the gift of ridiculous jokes is encouraged.

"The name of the game is to buy cheap and witty presents," Bond told the publication. "A gift is to make people laugh, not expensive.

Another gift rule is relevant when royalty opens presents. "These gifts will be opened on Christmas Eve, a German tradition that the family has kept for decades," Bond said.

Somewhat surprisingly, royal children do not dine at the same table as their parents on Christmas day.

"There are 7 tables, and the kids have their own little table in another room," revealed Mike Tindall, Zara Tindall's husband (via the sun).

Darren McGrady, the royal chef who cooked for both Princess Diana and Queen Elizabeth 2, confirmed the odd seating arrangement and (via the Independent) said: "(children) are not allowed to sit with adults until they learn the art of polite conversation.

When it comes to drinking alcohol, Bond advises against overdose. "The best champagne and wine will be served, but not everyone in the royal family is a heavy drinker anyway," she told the Sun.

While most families enjoy watching TV and playing board games during the Christmas holidays, that's not necessarily the case with royalty.

"Do not propose to play Monopoly.Bond told the Sun. As for the reasons, the former queen is said to have "thought it was too vicious," so instead the royals are playing charade. But Bond also pointed out that "a card game called Racing Demon" is another favorite activity, but "it can compete very hard."1

As for television, King Charles reportedly won't even let his relatives watch the King's Christmas speech broadcast on Christmas Day. "The King likes the family to be together on Christmas day and enjoy each other's company," Bond explained.

Sadly, members of the Royal Family cannot spend the entire holiday season in their pajamas.

"The Royals have a black tie dinner every Christmas Eve, so guests have to prepare," Bond told the outlet. "Then on Christmas day, the royal family should be properly dressed for church and then for lunch in the dining room."She continued, "This is not a black tie, but don't think the Royals are wearing room wear.

According to Bond, the annual Christmas Day church service can not be skipped. "Don't complain about going to church on Christmas morning, it's a tradition that goes back years," Bond revealed.

King Charles is known to be a little workaholic. But no matter how late the monarch is awake, the guests are not allowed to sleep until he says so.

"The King often works late, and he never really goes off-duty," Bond told the outlet. "Even if he decides not to work on Christmas day, his biological clock may not be in sync from all of the midnight he has,"
