Any tips on what to do in the evenings and weekend?
I read that it is coldest month of the year like 0 degree and wet snow. Something I have never experienced before. Any tips on clothings to carry? Living in Singapore I never wore even a jacket since a long long time.
Oh nice!

Well there's lots of pubs and bars, and a thriving live music and arts scene if that appeals. Perhaps you can find a 'What's on in Amsterdam' site?
You won't be starved of 'spice', as there is a notable Indonesian element in society there, dating back to their colonial days. So in your shoes I'd be looking into suggestions for Indon restaurants. Also the Dutch have a very outward and global perspective so I'm sure there'll be some authentic Sub-Con food to go and enjoy.
For sights to see etc, I'd look at Tripadvisor/Amsterdam/Attractions, and see what's top-rated.
Zero degrees, sheesh that's ok, it's forecast to be -16C here this weekend, before adding in wind-chill
For clothing, seeing as you have no single jackets that are viable you're going to have to rely on layering. So at an extreme that might be vest, t-shirt, shirt/polo-shirt, sweater, jacket.
For your legs get a pair of thermal 'long Johns', they're like girls leggings, made of stretchy cotton blend. They're not expensive and easy to find in Europe. That'll be a good starting point under any trousers.
For your feet, the heaviest foot-wear you have, that won't allow water to soak in.
Top it off with gloves, woolly hat, and a scarf, and you're set for the low arctic, never mind 0C. Though of course flying in from SG even 0C is probably going to feel like Siberia
p.s. when out carry a day-pack, so if you go and sit in a cafe/pub you can peel off a couple of layers and stow them away.
