Sorry. Assuming that he's in England then he's got a long wait for his bus pass.
In England, a woman becomes eligible for a bus pass when she reaches State Pension Age. To ensure equality, a man becomes eligible when a woman who was born on the same day as him reaches State Pension Age. That used to be 60 but is now gradually rising to 65 and then, along with that for men, to 66.
So, since a woman who shares a birth date with your friend won't qualify for her State Pension until around May 2020 (which is when your friend will also qualify for his State Pension).
If your friend is in Scotland, Wales or Northern Ireland he's already eligible for his bus pass but he has to apply for it (by contacting his local council); it's not automatic.
That information can be confirmed here:
