我如何排除周末golang

Question

I have this so far to count the number of days using http://golang.org/pkg/time/ but I don't know how to exclude weekends and only 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 to days
    days := int(diff.Hours() / 24)

    fmt.Printf("days  %d
", days)
}

Answer 1

Here's a simple little solution.

days := 0
for {
     if (t.Equal(f)) {
         return days
     }
     if (t.Weekday() != 6 && t.Weekday() != 7) {
          days++
     }
     t.Add(time.Hour*24)
}

You probably don't want to use your original t variable but keeping the example simple. I loop until t equals f, if they're equal I return my days count. If they're not I check to make sure it's a weekday and increment my days count if it is. I unconditionally add one day to my starting time.
