To celebrate National Breakfast Week (yes, that is a thing, don't question it), we've scoured the globe to see what people in different countries traditionally eat for the most important meal of the day.
Here we work our way around the clock, with the times shown representing the time in the UK as each world city wakes up...
Midnight - Tokyo, Japan
As the clock strikes midnight in the UK, the residents of Tokyo will be waking up and preparing for their day at work. The traditional Japanese breakfast consists of miso soup with plain rice and sides like natto (fermented soy beans), nori (seaweed) and tamagoyaki (a bit like omelette).
4.30am - Hyderabad, India
People in Hyderabad, southern India traditionally, breakfast on dosa - a crepe-type fried batter that is rolled and usually filled with potato (aloo). This is served with chutney and samba - a vegetable stew/curry.
7am - Jerusalem, Israel

Taking inspiration from the traditional Israeli farm - a Kibbutz - this style of breakfast is now served in hotels and restaurants across the country. Dishes like shakshouka - eggs cooked in a spicy tomato sauce - are common, as well as smoked or pickled fish, cheeses and fresh vegetables.
8am - Rome, Italy
No day in Italy is complete without coffee. The people of Rome start will usually start their day with a cappuccino at one of the city's busy espresso bars and breakfast, or "colazione", will be traditional continental fare - pastries, breads, cheeses, hams and fruit.
9am - London, UK

Whether it's in the local greasy spoon, a hotel departure lounge or in a five-star hotel - breakfast in the UK is dominated by the full English - any combination of bacon, eggs, sausage, mushrooms, beans, hash browns, tomatoes, black pudding (have we missed any?), accompanied with a healthy serving of toast and a mug of steaming hot tea.
9am- Dakar, Senegal
Residents of Dakar wake up with a cup of touba - a type of coffee spiked with a peppery grain called djar - accompanied with fruit and pastries or a baguette, a hangover of French rule.
9am - Reykjavik, Iceland

On the volcanic island in the bleak north Atlantic, a breakfast of hafragrautur (that's porridge to you and me) is served to warm the cockles, usually served with a sprinkling of sugar or a handful of raisins.
11am - Rio de Janeiro, Brazil
With influences from Africa, Portugal and other European countries, Brazil's cuisine has a unique blended identity. Breakfast consists of anything from fruit, tapioca flatbreads, requeijao (a ricotta-like cheese) and hams all washed down with a sickly sweet cup of coffee.
2pm - New York, US
As workers in London, Birmingham and Manchester head back to their desks after lunch, the busy worker bees of the Big Apple might just be grabbing an early brunch. From bagels smothered in cream cheese or eggs Benedict, the options are endless in the city that never sleeps.
5pm - Whistler, Canada
In the bustling ski resort of Whistler on Canada's west coast, residents and tourists need to fill up on a hearty breakfast. A stack of blueberry pancakes topped with crispy bacon and a (very generous) drizzle of maple syrup would be a good place to start.
7pm - Hawaii, US
On the small Pacific islands of Hawaii, spam is a surprise choice for breakfast. When served with a bed of rice and topped with a fried egg and gravy the ham-in-a-can dish becomes the much more appetising-sounding Loco Moco.
10pm - Sydney, Australia
As Britons are snuggling into bed, our cousins Down Under are rising (probably to a really warm, sunny day) and might tuck in a slice of toast covered with the nation's favourite yeast spread and a flat white - the antipodean coffee that's somewhere between a caffe macchiato and a latte.
