由于国务院放假安排每年可能都不一样，所以仅支持年以及三年前的数据，后续版本可能将支持手动添加放假数据
as holiday arrangement is defferent every year, it's arranged accroading to related govement files, we only support current year and passed 3 years calculation, may add manual data in the later versions
package main
import (
"github.com/Admingyu/go-workingday"
"log"
"time"
)
func main() {
dt := time.Now()
region := "CN"
isWork, dayType := workingday.IsWorkDay(dt, region)
log.Print("现在是：", dt)
log.Print("地区：", region)
log.Print("今天需要上班？", isWork)
log.Print("原因：", dayType)
}
