Daylight hours in Saskatoon

Saskatoon gets 16h 44m of daylight on its longest day in June, and 7h 45m on its shortest in December — a difference of 8h 59m across the year.

How fast the days change

Around 17 March, Saskatoon gains or loses about 4.1 minutes of daylight every day.

That is quick enough to notice week to week, which is why spring seems to arrive all at once this far from the equator.

Solstices and equinoxes

March equinox 20 Mar 07:08 19:19 12h 11m
June solstice 21 Jun 04:45 21:31 16h 45m

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.
