How Does A Person Observe Fasting In Polar Regions?

How does a person observe fasting in polar regions?

In polar regions where times for prayer and fasting are not formed completely or partly, acts of worship are performed by taking into account the times of the closest place where these times are formed normally or with discretion by considering the other religious examples (Ibn Abidin, Radd al-Muhtar, II, 18-23). After saying that when the Day of Judgment approaches, the days will get longer, a day will last for a year, a day for a month, and a day for a week, the Prophet (saw) stated that prayers will be determined in those days, that is, the times will be predicted/determined by making comparisons and measurements and performed accordingly. (Abu Dawud, Malahim, 14).
