If you lived at latitude 45 degrees on uranus, for what fraction of a uranian year would the longest winter night last?

If you are in Uranus with an titled angle of 97.77°, living in the latitude 45° would mean experiencing a winter night at almost one third of a Uranian year. A year in Uranus is equivalent to 84 earth years, meaning it would be winter for 28 earth year at latitude 45°
