go - How can I exclude weekends golang -

i have far count number of days using http://golang.org/pkg/time/ don't know how exclude weekends , count business days

package main  import (     "fmt"     "time" )  func main() {     t := time.now()     f := time.date(2015, time.august, 21, 24, 0, 0, 0, time.utc)     diff := f.sub(t)      // convert diff days     days := int(diff.hours() / 24)      fmt.printf("days  %d\n", days) } 

here's simple little solution.

days := 0 {      if (t.equal(f)) {          return days      }      if (t.weekday() != 6 && t.weekday() != 7) {           days++      }      t.add(time.hour*24) } 

you don't want use original t variable keeping example simple. loop until t equals f, if they're equal return days count. if they're not check make sure it's weekday , increment days count if is. unconditionally add 1 day starting time.
