You can train your abs daily if they don't hurt. The abdominals are a very fatigue-resistant muscle group because they're primarily made of slow-twitch fibers. Not only will they be well recovered within 24 hours, but after 15 seconds of rest they should be recovered to the point that you can perform more reps. It's difficult to overload the abdominal muscles to the degree that you reach hypertrophy, or an increase in size. For well-developed abs, expect to spend about 15 minutes a day on your abs routine.
