Oh How the Darkness Creeps Up

I'm sitting at home, half watching television and half surfing the internet, when I think to myself, better get up to bed.  A quick look at the clock reveals it's only just gone ten o'clock.  How can that be when it's been dark for so long, already.  As i'm not heavily engaged in anything I have a quick look for an online sunrise and sunset table for the month only to find, to my amazement, that it's getting darker by nearly four minutes per day.  Four minutes per day, That's a lot.

In ten days it will be nearly forty minutes darker per day and by the end of the month over an hour less of glorious autumunal sunlight will be falling on us each and every day.  Check out the table below, then follow this link to see for yourself.  Call me nerdy but I found it fascinating.


Think on the bright side, it'll be four seconds lighter on 22nd December than on 21st.

Ah those light nights........
