Go has no enums and type weekday has no permitted/not permitted values.
You have to check for valid values manually. Sometimes using a map is a
good approach, sometimes a switch may be more appropriate.
For numeric intervals an if statement will work best so sometimes it's
better to have symbolic names for the permitted values and use the stringer
utility to attach a String() method to them.
type Weekday int // or perhaps uint
const (
Monday Weekday = iota
Tuiesday
Wednesday
...
Sunday
)
