I work full time and never really 'stop' in evenings and weekends. Most of my spare time is spent doing: Dogwalking, car-booting, Auctions, cooking, cleaning, shopping, visiting friends & Family, meals out, DIY, photography, visiting airshows/ garden shows, gardening, helping MIL with allotment. There's the inevitable weddings/ christenings/ baby showers to attend in spring/ summer.
I've also started making patchwork quilts for friends who are about to have a baby - so that's taken up a lot of my time recently.
I'm not a social person really so have to 'push' myself to get out and about, otherwise I'd just sit on the internet all day and 'stew' - But there's nothing wrong with having a bit of down time to slouch and internet surf too :-)
I do try and look up 'Things to do' on the local council pages, but a lot of days out are organised through word of mouth.
