In seven years' time, Muslims around the world will observe Ramadan twice in one year – a phenomenon that last occurred in 1997.
Dr Hasan Al Hariri, chief executive of the Dubai Astronomy Group, said those observing the holy month in 2030 will commence their fast twice, first in January and then again in late December.
This is because the Islamic Hijri calendar is based on lunar cycles and it takes 33 years to complete a full cycle.

“The lunar calendar, or a lunar-based year, is 11 days shorter than the solar calendar,” he said.
“So, for example, a full year is 354 days instead of the 365 days marked on the Gregorian calendar.
“Because of that, for each year that passes, Ramadan moves back by 10 or 11 days.
“This phenomenon makes it unique, where in one solar year we will have two Ramadans. The next time this happens will be in 2030.”

Dr Al Hariri said while from a "solar calendar perspective" the holy month will be marked twice in one year, from a lunar calendar standpoint it will still occur only once within a 354-day cycle.
He said the number of days of Muslim fasts during Ramadan will not change in 2030, as it is always a 29 or 30-day period, depending on the moon sighting.
How is the start of the holy month determined?
Ramadan is observed by more than 1.8 billion Muslims around the world and is believed to be the month when the Quran was revealed to the Prophet Mohammed.
The sighting of the Moon signifies the start and the end of Ramadan, the ninth month of the Islamic calendar.
In the days leading up to the holy month, religious authorities in the Middle East scan the night sky for the first glimpse of a crescent moon, heralding the start of Ramadan.
In 2030, it is expected that Ramadan will begin in early January and then again in late December.
The twice-yearly observance is due to happen again in 2063.

TEACHERS' PAY - WHAT YOU NEED TO KNOW
Pay varies significantly depending on the school, its rating and the curriculum. Here's a rough guide as of January 2021:
- top end schools tend to pay Dh16,000-17,000 a month - plus a monthly housing allowance of up to Dh6,000. These tend to be British curriculum schools rated 'outstanding' or 'very good', followed by American schools
- average salary across curriculums and skill levels is about Dh10,000, recruiters say
- it is becoming more common for schools to provide accommodation, sometimes in an apartment block with other teachers, rather than hand teachers a cash housing allowance
- some strong performing schools have cut back on salaries since the pandemic began, sometimes offering Dh16,000 including the housing allowance, which reflects the slump in rental costs, and sheer demand for jobs
- maths and science teachers are most in demand and some schools will pay up to Dh3,000 more than other teachers in recognition of their technical skills
- at the other end of the market, teachers in some Indian schools, where fees are lower and competition among applicants is intense, can be paid as low as Dh3,000 per month
- in Indian schools, it has also become common for teachers to share residential accommodation, living in a block with colleagues

“Don’t make the mistake of thinking you can ride as fast or as far during the summer as you do in cooler weather. The heat will make you expend more energy to maintain a speed that might normally be comfortable, so pace yourself when riding during the hotter parts of the day.”

Torno Subito by Massimo Bottura
When the W Dubai – The Palm hotel opens at the end of this year, one of the highlights will be Massimo Bottura’s new restaurant, Torno Subito, which promises “to take guests on a journey back to 1960s Italy”. It is the three Michelinstarred chef’s first venture in Dubai and should be every bit as ambitious as you would expect from the man whose restaurant in Italy, Osteria Francescana, was crowned number one in this year’s list of the World’s 50 Best Restaurants.
Akira Back Dubai
Another exciting opening at the W Dubai – The Palm hotel is South Korean chef Akira Back’s new restaurant, which will continue to showcase some of the finest Asian food in the world. Back, whose Seoul restaurant, Dosa, won a Michelin star last year, describes his menu as, “an innovative Japanese cuisine prepared with a Korean accent”.
Dinner by Heston Blumenthal
The highly experimental chef, whose dishes are as much about spectacle as taste, opens his first restaurant in Dubai next year. Housed at The Royal Atlantis Resort & Residences, Dinner by Heston Blumenthal will feature contemporary twists on recipes that date back to the 1300s, including goats’ milk cheesecake. Always remember with a Blumenthal dish: nothing is quite as it seems.

Essentials
The flights
Whether you trek after mountain gorillas in Rwanda, Uganda or the Congo, the most convenient international airport is in Rwanda’s capital city, Kigali. There are direct flights from Dubai a couple of days a week with RwandAir. Otherwise, an indirect route is available via Nairobi with Kenya Airways. Flydubai flies to Kinshasa in the Democratic Republic of Congo, via Entebbe in Uganda. Expect to pay from US$350 (Dh1,286) return, including taxes.
The tours
Superb ape-watching tours that take in all three gorilla countries mentioned above are run by Natural World Safaris. In September, the company will be operating a unique Ugandan ape safari guided by well-known primatologist Ben Garrod.
In the Democratic Republic of Congo, local operator Kivu Travel can organise pretty much any kind of safari throughout the Virunga National Park and elsewhere in eastern Congo.
The burning issue
The internal combustion engine is facing a watershed moment – major manufacturer Volvo is to stop producing petroleum-powered vehicles by 2021 and countries in Europe, including the UK, have vowed to ban their sale before 2040. The National takes a look at the story of one of the most successful technologies of the last 100 years and how it has impacted life in the UAE.
