If you are like me, you want to know when the sun rises and sets locally. This calculator may be what you need. Here, near Cambridge, the nights start to get lighter from this coming Thursday (Dec 18th) although it is not until Jan 10th until the mornings start to get lighter.
I much prefer light evenings.
