time.Time.YearDay() Function in Golang with Examples

In Go language, time packages supplies functionality for determining as well as viewing time. The Time.YearDay() function in Go language is used to find the day of the year as provided by “t”. Where, the range for non-leap years is [1, 365] and for leap years it is [1, 366]. Moreover, this function is defined under the time package. Here, you need to import the “time” package in order to use these functions.

Syntax:

func (t Time) YearDay() int

Here, “t” is the stated time.

Return value: It returns the day of the year as specified by “t”.

Example 1:

// Golang program to illustrate the usage of
// Time.YearDay() function

// Including main package
package main

// Importing fmt and time
import "fmt"
import "time"

// Calling main
func main() {

    // Declaring t in UTC
    t := time.Date(2019, 6, 5, 11,
              35, 04, 0, time.UTC)

    // Calling YearDay method
    yrday := t.YearDay()

    // Prints the day
    // of the year as specified
    fmt.Printf("The day of the year "+
      "in the 't' specified is: %v\n", yrday)
}

Output:

The day of the year in the 't' specified is: 156

Example 2:

// Golang program to illustrate the usage of
// Time.YearDay() function

// Including main package
package main

// Importing fmt and time
import "fmt"
import "time"

// Calling main
func main() {

    // Declaring t in UTC
    t := time.Date(2020, 35, 60,
       45, 67, 94, 7567, time.UTC)

    // Calling YearDay method
    yrday := t.YearDay()

    // Prints the day of the year as specified
    fmt.Printf("The day of the year in "+
      "the 't' specified is: %v\n", yrday)
}

Output:

The day of the year in the 't' specified is: 365

Here, the “t” stated above has values that are out of usual range but they are normalized while conversion.
