In the Air Force, after you arrive to your first duty station, when can you take your earn leave days?

After you arrive to your first duty station, when can you take your leave days. Because I will arrive at my first duty station in April, Charleston, SC. But I'm getting married in Illinois on August 11. So that means I would be at my first duty station for 2 months, before I would have to go to Illinois and get married. Any thoughts!
