A polar day refers to a day when the sun does not set for 24 hours. This occurs because the top of the earth tilts toward the sun during one half of the year. Areas in the very northern and very southern parts of the globe are the only regions that experience both polar days and polar nights.
Solstices occur when Earth's axis is pointed directly toward our Sun. This happens twice a year during Earth's orbit. Near June 21 the north pole is tilted 23.5 degrees toward our Sun and the northern hemisphere experiences summer solstice, the longest day of the northern hemisphere year.
