6th string (E)--lower 1 and 1/2 steps

5th string (A)--lower 1/2 step

4th string (D)-raise 1 step

3rd string (G)-lower 1/2 step

2nd string (B)-tune normally

1st string (E)-lower 1/2 step

Or just find a piano as the other person suggested

I'm really curious about what you are planning to play with this odd tuning.

The best thing I can think of is downloading an app on your phone (there are tons of tuning apps) or if you have a piano you can play the note of there and tune it by ear that way (I do that a lot and it's pretty effective). There are also YouTube videos and websites online where you can play particular notes and tune by ear.
