The Islamic religion is easy and not difficult
Muslims living in places where the sun never rises for MONTHS.
the prophet informs us that we should not follow the movement of the sun, but calculate the time as for normal regions
they can fast for Ramadan by following the sunrise and sunset times in Mecca.
The same applies to prayer times.
Some scholars say that in this case one should follow the timetables of Mecca or Medina, land of Revelation, while others suggest following the nearest "normal" region.
This applies to all obligations: the fulfillment of prayers, the payment of zakat and ramadan etc.
for the direction of the qibla, it is enough to have a compass ... not too complicated
