With less than a week until the holy month of Ramadan, Muslims globally are gearing up to observe fasting as part of their religious duty. Over a billion believers are anticipated to fast during daylight hours, marking a sacred period of spiritual reflection and devotion. The commencement of Ramadan varies each year, and this time it arrives earlier, aligning with shorter and cooler days in many regions worldwide. Fasting durations will differ across countries, ranging from 12 to over 17 hours. Notably, countries like Chile, New Zealand, Argentina, and South Africa will experience relatively shorter fasting periods, while Finland, Greenland, and Iceland will endure longer fasting durations, averaging around 17 hours per day.
