Thanks, you've given me the chance to use the word crepuscular!

So gloaming means effectively 'dusk' ?

Not quite the same ? Crepuscular means active at dawn and dusk, rather than just dusk. Cats are crepuscular.

There is a song popularised by Sir Harry Lauder - 'Roamin' in the Gloamin'. It's a bit cringeworthy so here's a (barely) acceptable more intelligible version from Kenneth McKellar -

Thanks for the clarification, Tripps. You prompted me to look at Wikipedia and I've found a couple more words to try out...
In zoology, a crepuscular animal is one that is active primarily during the twilight period,[1] being matutinal (active during dawn), vespertine/vespertinal (active during dusk), or both. This is distinguished from diurnal and nocturnal behaviour, where an animal is active during the hours of daytime and of night, respectively. Some crepuscular animals may also be active by moonlight or during an overcast day.

I think I could be described as matutinal....
