Two-thirds (roughly) of the way between the Equinox and the Solstice:
Sunrise: 06:43:57
Solar Noon: 12:06:54
Sunset: 17:29:51
Peak Sun Angle: 43.88 degrees
Length of Day: 10:45:54
We're now under the 45 degree sun angle mark, so definitely winter-like sun angles and day lengths right now. Sun angle has dropped 20.15 degrees since the equinox, and ginormous 43.51 degrees since the solstice, we've also lost 82.5 mins of daylight since the equinox and 181.5 (3 hrs 1.5 mins) of daylight since the equinox. There's about 3.48 degrees to go until the peak sun angle on the solstice, so we're about 93% of the way between summer and winter solstice in terms of sun angle.
Sun is directly overhead at 20.02 S, and on the horizon at 69.98 N.
Sun angle at this very moment (3:44 PM) is 20.01 degrees, equivalent to solar noon at 49.97 N.
BTW - the sun angle dropped below 45 degrees for the first time on 17 November, it will be that way until 24 January.

November 27th in Saskatoon: Sunrise: 8:47am Sunset: 5:01pm Total day length: 8:13:55 Solar noon: 12:54pm Peak sun angle: 16.7° Days are getting very short now. I leave for work in the dark and I get home from work almost in the dark. Thankfully there's not much more daylight left to lose, and in less than a month the days start getting longer  |

Does anyone know why sunrise/sunset times are offset in terms of when they hit their peaks? Here the sunset is at its earliest time from December 8th to 17th and then starts to get later again, while the sunrise continues to get later until December 26th and doesn't start getting earlier again until January 4th, at which point the sunset has already regained 14 minutes compared to its earliest.
The effect is even more pronounced in some other places, for instance in Mexico City the sunset is at its earliest from November 19th to December 2nd, while the sunrise is at is latest from January 12th to 23rd, nearly two months of difference.
What's the cause of this?

The time of solar noon changes from day to day, and around the solstices, the change in solar noon times are very significant compared to the change in sunrise and sunset times. |

It's also dependent on latitude, I think nei linked such a map of North America once. Different latitudes reach their earliest sunsets at different times. |

Different latitudes reach their earliest sunsets at different times. solar noon being earlier or later shifts the same worldwide. But higher latitudes obviously are more affected by the days getting shorter than lower latitudes. Higher latitudes will have earlier sunsets closer to the solstice while lower ones, while lower latitude places the time will be further from the solstice as solar noon timing changes are larger relative to the relatively small daylength changes. In the equator, only solar noon changing causes a change in sunrise/sunset change as the daylength is the same yeararound. |

the exact parallels for certain day lenghts at winter and summer solstice. got the data from here: www.esrl.noaa.gov/gmd/grad/solcalc/sunrise.htmlsummer solstice 13h 14°34'N 14h 28°54'N 15h 39°56'N 16h 47°45'N 17h 53°17'N 18h 57°25'N 19h 60°20'N 20h 62°28'N 21h 63°58'N 22h 64°58'N 23h 65°32'50"N 24h 65°43'55"N (no apparent sunset) winter solstice 0h 67°24'N (no apparent sunrise or sunset) 1h 67°13'25"N 2h 66°41'N 3h 65°45'N 4h 64°20'N 5h 62°20'N 6h 59°35'N 7h 55°50'N 8h 50°23'N 9h 42°55'N 10h 32°35'N 11h 18°55'N |

Last day of November!
Sunrise: 06:50:36
Solar Noon: 12:09:44
Sunset: 17:28:53
Peak Sun Angle: 42.18 degrees
Length of Day: 10:38:17
Very winter-like sun angles and day lengths right now! Sun angle has dropped by 21.85 degrees since the equinox and 45.21 degrees since the summer solstice, conversely we have lost 90 minutes of daylight since the equinox and 189 mins (3 hrs 9 mins) since the solstice. There's only 1.78 degrees left in the sun angle drop until the solstice, so we're about 97% of the way between the summer solstice and winter solstice in terms of sun angle.
Sun angle is directly overhead at 21.72 S and on the horizon at 68.28 N.
Sun angle at the moment (8:06 am) is at 14.04 degrees, same as solar noon at 54.24 N.

The sun has already set today so this is for tomorrow:
Sunrise: 8:53
Sunset: 15:26
Day length: 6 h 33 min
Peak sun angle: 8,6°
Earliest sunsets are less than two weeks away, there's about half an hour of daylight left to lose. With snow on the ground the darkness doesn't bother me yet.
