It depends on which pokemon.
Now sometimes it is at least a day.
If u have action replay there is a code for fast

It needs to be level 16 to evolve.
Pretty easy. They don't.
2 years
It'll evolve at level 40. It may take awhile.
It evolves by trade,not level. So, it's your choice when you to evolve it.
A couple battles.
All you need to do it is evolve it with a Fire Stone. No leveling up is required, but recommended.
Approximately 2 hours
just give the right stone to it and it will evolve straight away e.g. eevee+firestone =flareon
A chao evolves in 2 ways. To get a dark chao it will evolve when you have made it have a dark wing. To get a hero chao then it will evolve when you have made two balls on his head connect.
There is no quick way, Dragonair will take a long time to evolve...
You need to Link trade the Electabuzz, and hopefully that same person will trade it back to you.
