Happy birthday
emperor!
Which reminds me, equinox tomorrow. I looked it up, it's at 03:09 UTC, which I guess is when the sun checks into the southern hemisphere, somewhere to the east of Indonesia, I think. Or in less anthropomorphic, geocentric terms, when the equator crosses the line from the centre of the sun to the centre of the Earth, with the intersection being somewhere to the east of Indonesia.
Anyway, the rate at which the days (in the (shrinking regions of the) northern hemisphere (where they still have days)) will be getting shorter will start slowing down, so we have that to celebrate. Or if you like darkness, it's soon going to be the dark half of the year. Either way, it's good news.

These are interesting, especially the "sun's path in the sky" charts, which show that the real problem I face here in Finland in the winter is that although there is supposedly 4 hours of daylight the sun barely manages to limp above the horizon, and is therefore blocked by the trees and apartment buildings.

...but as you say, the low sun in Findland means that the quality of daylight during daylight hours is low, so I guess it all balances out somehow.
