So I was thinking about fasting and how you don't eat or drink from sunrise to sunset. But what if you lived in the north (like northern Alaska and the like) where it's light outside 24 hours a day sometimes, especially around the summer solstice? And what if Ramadan fell on the time period where it's dark 24 hours up there? Would you fast the whole day or just part of it? I don't live where this is the case, I was just wondering about it.
