Hi, I tested the same code on my local machine and it worked.

type Hours int

func (h *Hours) Increment() Hours { return (*h + 1) % 24 }

src/clock/hours.go 
package clock

type Hours int

func (h *Hours) Increment() Hours {
  return (*h + 1) % 24
}

Pay attention to what the challenge is asking you to do here. Remember, it wants to be able to use your Increment method like this:

hours := Hours(23)
hours.Increment()
fmt.Println(hours) // Prints "0"

Notice how it doesn't want your method to return anything, but just operate on the value directly. When your code is changed accordingly, it passes the challenge for me

Thanks,

I guess I should have read the instructions the instructions more carefully.
