That how will a person do iftar and sehari in areas where the sun is out for six months and then it sets for six months

Would your question regarding sunrise and sunset be applied to on cloudy days when it is not always clearly evident when either occurs?


On cloudy days the fast should be broken with some delay till it is definite that the sun would have set. The watches or clocks should not be relied upon as they may go wrong. Even if someone has called the Azaan and the setting of sun is still doubtful, fast should not be opened till your own heart is satisfied about the time.
