The winter solstice is the day of the year that has the least daylight hours of any in the year and usually occurs on 22 June but can occur between 21 and 23 June.
This year the Southern Hemisphere Winter Solstice is on Saturday, 22 June 2019 at 1:54 am AEST.
At solstice the Earth’s orbit reaches the place where the southern axis is as far away from the sun as possible. Therefore we down under theoretically should see a little more of the Sun. But not quite as much as you might think and it has all to do with the Solar Day.
So we getter slightly later sunsets but sunrises not so much for a little while anyway.
Unfortunately this doesn’t mean that the Sun will rise earlier on Sunday
