What Does Daylight Mean?
Here's 9:05 am this morning. Only two and a half weeks after the solstice and it's light at 9 am in Anchorage.
The Anchorage Daily News has a Daylight feature in the weather section. But that focuses on sunrise to sunset. But we have long, long twilights this far north, so we really have more 'daylight' than the sunrise to sunset time suggests. In the picture above, it is still an hour before the sunrise, yet the sky is no longer dark. And the same is true on the other end of the day. When it is cloudy, we have much less 'daylight' of course.
Anyway, yesterday we gained 3 minutes and 25 seconds of official daylight. By March we'll be galloping along, gaining almost 6 minutes a day. You can really feel the change in the light here, even though it was -10˚F when I took this picture this morning, we know spring is on the way. You can see the temperatures are way below normal - which is between the blue and yellow lines in the middle chart.
And for J and me, spring will be Monday afternoon (Anchorage time) when we get off the plane in Chiang Mai.

The temperature is between -10 and -20 Celsius outside. We still have gas to heat our homes but there are some restrictions in public institutions and some factories are temporary closed. We sent some gas to Serbia because they have nothing. Hungary is one of the few countries which has gas now because we saved some for crisis so Hungary is in the best position in Eastern Europe concerning gas.
