Radio silence

Apologies for the lack of communication in recent weeks. I've been finalising a temporary role and recently my home computer has decided it can't find the internet. When my resident computer expert has a moment the problem will be rectified, so I'll probably be back ranting on Friday. Before sundown, of course. I've got to find a website which tells me when exactly this is; what with all the running around I need to do before Shabbat, I'll need to plan candle-lighting with military precision.

If anyone knows where to find a Jewish calendar online, with details of sunrise/ sunset, I'd be grateful for the details!
