Anytime you can get out is a good time to go. They are more active in the morning and evening though. You don't want the wind to be blowing a gale either or they can't here the call. Where you are just started you could save some money and get a cheap mouth call. I use a Tally Ho. They are less than $10 and I have shot more coyotes using that call than any other that I have. If you are willing to spend some money Foxpro is an awesome electronic call. The benefit of electronics is that you can set them up a little way away from you and the coyotes are focused on them rather than on you. It allows you to move a little bit more, but you still need to move as little as possible. Good luck!!! Its a learning game, but extremely fun!
