Sunrise Sunset Times Note: When you select Sunrise or Sunset It does not mean that the Start is exactly at the sunrise time, or the End at exactly at the sunset times. You can select any time window.

When the days get longer, the sunrise rise time will be earlier each day and the sunset time will be later.
