What are the hours of daylight in autumn and spring Antarctica?

During the Antarctic autumn (March to May), the hours of daylight gradually decrease until the sun finally sets on the longest night of the year (the winter solstice), which occurs around June 21. Conversely, during the Antarctic spring (September to November), the hours of daylight progressively increase until the sun finally rises on the longest day of the year (the summer solstice), which falls around December 21. At the exact times of the solstices, Antarctica experiences continuous darkness during winter and continuous daylight during the summer.
