In 2030, Muslims will experience a rare "double Ramadan," fasting twice within the Gregorian calendar year (early January and late December) due to the lunar Islamic calendar's shift; demographic trends suggest continued significant growth, with India potentially having the largest Muslim population and substantial increases in Europe and the U.S., while religious practices will focus on increased devotion and reflection during these two holy months.
