To evolve Eevee to Espeon and/or Umbreon it's a little harder. You need to raise Eevee's IQ to like around 4 stars, and then use the Lunar Ribbon for Umbreon and a Solar Ribbon for Espeon.

Ruby and Sapphire Since there is no day and night, you might be puzzled by how you can evolve your Eevee in R/S/E, but even though there are no visible day and night, Eevee will evolve into Espeon from noon to midnight, and into Umbreon from midnight to noon.

You can only evolve Eevee into Umbreon or Espeon in Generation 2 or later games. This is because there is no time element in the original games, or in FireRed and LeafGreen.

How to get Eevee to evolve into Umbreon: Train Eevee and give base items such as Carbos, Iron, Protein, etc to Eevee so it's happiness will increase. Even if you have a Soothe Bell, that may work as well. If you have a rare candy, use it on Eevee at 12:00 PM. Then it will evolve into Umbreon.

You need the specific item for evolution, and if you want Umbreon or Espeon you will need to raise its IQ to 2 stars. If you want a glaceon then get the icy rock (or whatever its called) and beat all the post game stuff. Then you can evolve Eevee at luminous spring.

If you can, try to level your Eevee up to 33 so you can acquire moves like Baton Pass, which are quite useful when paired with Umbreon. Then, just wander around the grass at night, battling and grooming until your Pokemon finally evolves into a gorgeous looking Umbreon.

In order to get Eevee to evolve into either Espeon or Umbreon, you'll need to raise its Friendship level to at least 220. A common way to increase Friendship is to just keep Eevee in your party as you walk around. You'll gain 1 Friendship every 512 steps you take in the game.

The best time to evolve Eevee is just when you get it, in Celadon Department Store buy a Water/Thunder/Fire Stone and to evolve it right away. To get Umbreon or Espeon, a good way to evolve him earlier is to give him 10 Proteins and other things like this and it will be an Umbreon/Espeon level 26.

Level up Eevee at during the day (Espeon) or during the night (Umbreon) once you think its Friendship is at 220. Once you think that your Eevee is above 220 Friendship, level it up in the day time to get Espeon, or level it up at night to get Umbreon.
