No. Days get longer for half a year, starting from the middle of winter. Then, from the middle of summer, they start getting shorter again.The length of a given day increases from the winter solstice (shortest day of the year) to the summer solstice (longest day of the year). The length decreases from midsummer to midwinter.If winter is defined as the period from the winter solstice to the vernal equinox, and spring as the period from the vernal equinox to the summer solstice, then the length of a solar day increases during winter and spring, and decreases in summer and fall (i.e. from midsummer to midwinter).
