For Muslims around the world, the arrival of the holy month of Ramadan is both a cause for celebration as well as a means of fulfilling one of the five pillars of Islam, namely the Ramadan fast. 

Although the Ramadan fasting hours vary around the world, they can generally be described as ‘from dawn till dusk,’ meaning that Muslims are not allowed to drink, eat, and engage in husband-wife intimacy for as long as the sun is still out.

Depending on where they are, the Ramadan fasting period can get quite punishing, as the daylight hours in some regions can last up to 18 hours!

Let’s take a look at some of the regions with the longest and shortest fasting hours around the world in 2024.

When is Ramadan 2024?

The arrival of Ramadan has always been associated with a certain amount of mystique and contemplation. The exact date of the month’s beginning is traditionally determined by religious scholars/authorities under the cover of night as they seek to observe certain sightings related to the appearance and cycle of the moon.

For the year 2024, the Holy Month of Ramadan will commence on 11th March, according to the predictions. 

It’s important to note, however, that due to the cycle of the moon, Ramadan dates vary in different countries, albeit typically only by a day. So, the answer to the question of when Ramadan 2024 starts would largely depend on where you live.

Many other countries celebrating Ramadan are likely to also observe the Holy Month starting from the 12th of March.

Essentially, the difference in fasting hours is due to the varying length of the day from one region to another. This has to do with the time of the year, distance from the equator, and some other sciency stuff that makes the sun appear longer or shorter depending on where you are.
