Daylight ChartThe fluctuation in the time of sunrise and sunset throughout 2025 in Douglas, Isle of Man is illustrated in the following chart. Note that the disjointed nature of the graph during late March and October is caused by the switch to daylight saving time for the summer months – the time at which this occurs fluctuates slightly from year to year. The mauve bands between night and day represent the civil twilight just before sunrise and just after sunset during which the sun is below the horizon but on a clear day it is still considered bright enough to work outside without artificial lighting. |
