Simple, how can we calculate the what percentage of the year is gone.

perc.go

package main

/** how to calculate the percentage of the year in go */

import (
        "fmt"
        "time"
)

func main() {
        t := time.Now()
        yearday := t.YearDay()
        // TODO: What if we are in a leap year
        perc := (float64(yearday) / float64(365)) * 100
        year := t.Year()
        fmt.Printf("YearDay: %v \n", yearday)
        fmt.Printf("Year: %v \n", year)
        fmt.Printf("Perc: %f \n", perc)
}
