Antarctica. Seriously. Desserts are classified as places that get less then 254mm of rain a year. The Sahara gets 25mm of rain a year. Antarctica gets only 2% of this. There are places in Antarctica where it hasn't rained for over 400 years.
It is day for you when your place on earth is facing sun. Later, it will be day for someone else, when HIS place on earth is facing sun. Some place on earth is always facing sun; it is day for the people there.
