The month of Ramadan started June 6th 2016 for the Hijri year 1437. We have dawn starting at 4am and sunset/dusk around 830pm.
Some of the longer fasting for sure! All prayers go out to those in areas that observe the long 19 hour days!
Muslims in the UK could be left fasting for 19 hours a day, as the holy month of Ramadan coincides with the summer solstice in the northern hemisphere.
