How Long Do Muslims Fast Around the World?
Explore how fasting hours differ globally — from 11-hour fasts near the equator to nearly 20 hours in northern regions.
During the month of Ramadan, Muslims fast each day from dawn (Fajr) until sunset (Maghrib). While this rule is the same everywhere, the actual length of the daily fast can vary significantly depending on where someone lives.
In some parts of the world, fasting may last around 11 hours, while in others it can stretch to 18 or even 20 hours. These differences occur because the timing of sunrise and sunset changes across the globe based on geography, seasons, and the position of the sun.
Understanding how fasting hours vary worldwide helps explain why the Ramadan experience can feel quite different depending on location.
The Basic Rule of Ramadan Fasting
The daily fast during Ramadan follows a simple schedule:
- Fasting begins at Fajr, when the first light of dawn appears.
- Fasting ends at Maghrib, when the sun sets.
This means that the length of the fast is essentially the number of daylight hours between dawn and sunset.
Because sunrise and sunset occur at different times across the Earth, fasting hours naturally vary from place to place.
Why Fasting Length Changes by Location
Several geographic factors influence how long Muslims fast during Ramadan.
Latitude
Latitude measures how far a place is located north or south of the equator. It plays the biggest role in determining daylight length.
Locations close to the equator experience fairly consistent day lengths throughout the year. Places further north or south experience larger seasonal changes, with longer days in summer and shorter days in winter.
Because fasting lasts from dawn to sunset, longer daylight means longer fasting hours.
Seasonal Timing of Ramadan
Ramadan follows the Islamic calendar, which is based on lunar cycles. The lunar year is shorter than the solar year, so Ramadan moves earlier by about 10–11 days each year on the Gregorian calendar.
This means Ramadan gradually moves through every season over a cycle of about 33 years.
When Ramadan falls in summer in the Northern Hemisphere, days are longer and fasting hours increase. When it falls in winter, the fasting period tends to be shorter.
Time Zones and Local Geography
Time zones and local geographic conditions can also affect sunrise and sunset times slightly. Coastal locations, mountain elevations, and a city's position within a time zone can all influence the exact timing of solar events.
Typical Fasting Hours Around the World
Although exact fasting lengths change slightly each day during Ramadan, general patterns can be seen across different regions.
Near the Equator
Cities close to the equator experience relatively stable daylight hours year-round.
In places such as:
- Jakarta
- Kuala Lumpur
- Nairobi
In equatorial regions like Indonesia and Malaysia, fasting typically lasts around 12 to 13 hours regardless of the time of year.
Because the day length changes very little in equatorial regions, fasting durations remain fairly consistent each Ramadan.
Middle Latitudes
Many major Muslim population centres are located in mid-latitude regions where day length varies more noticeably across seasons.
Examples include cities such as:
In these locations, fasting hours may range from about 12 hours in winter Ramadan months to 16 or 17 hours when Ramadan occurs in summer.
The variation depends largely on when Ramadan falls during the year.
Northern Regions
In northern countries where summer days are very long, fasting durations can become much longer.
Cities such as:
can experience fasting periods approaching 18 to 20 hours when Ramadan falls near the summer solstice.
This occurs because the sun remains above the horizon for much longer during the summer months at higher latitudes.
How Fasting Times Change During the Month
Even within the same city, fasting length changes slightly from day to day during Ramadan.
This happens because sunrise and sunset shift gradually throughout the month as the Earth continues its orbit around the sun.
As a result:
- Dawn may occur a little earlier each day.
- Sunset may occur slightly later or earlier depending on the season.
These small daily shifts are why Ramadan timetables display slightly different fasting hours for each day.
High-Latitude Challenges
In some locations near the Arctic Circle, daylight patterns become extreme during summer.
Places such as:
- Tromsø
may experience periods when the sun barely sets or does not set at all.
When Ramadan occurs near these periods, determining fasting times can become more complex. Islamic scholars have developed different approaches for these situations, such as following the timetable of a nearby city with normal sunrise and sunset cycles.
These methods allow Muslims living in high-latitude regions to observe Ramadan in a practical and meaningful way.
A Shared Practice With Different Experiences
Although fasting hours vary widely around the world, the core practice of Ramadan remains the same everywhere: abstaining from food and drink from dawn until sunset.
For some people, the daily fast may last just over half the day, while for others it can extend close to twenty hours. Over time, as Ramadan moves through different seasons, communities experience these variations in different ways.
This global diversity reflects the connection between the Ramadan fast and the natural movement of the sun — a rhythm that shapes daily life for Muslims across many climates and regions.
