Daylight hours in Darwin

Darwin gets 12h 51m of daylight on its longest day in December, and 11h 24m on its shortest in June — a difference of 1h 27m across the year.

How fast the days change

Around 17 March, Darwin gains or loses about 0.7 minutes of daylight every day.

Barely perceptible — near the equator the length of the day hardly changes at all, and the seasons announce themselves through rain and heat instead.

Solstices and equinoxes

June solstice 21 Jun 07:06 18:30 11h 23m

The equinoxes give almost exactly twelve hours of daylight everywhere on earth — "almost" because sunrise is defined by the sun's upper edge rather than its centre, and the atmosphere bends its light over the horizon before it has really arrived. Both lengthen the day by a few minutes.

Assumptions

  • Sea-level horizon. Hills, mountains and buildings all delay sunrise and bring sunset forward, sometimes by a lot in a valley.
  • Standard refraction. Sunrise is taken at −0.833°, allowing for the sun's disc and average atmospheric bending. Unusual air conditions shift it by a minute or two.
  • Local clock time, with daylight saving applied from the IANA timezone database.
