How to Print Specific date-time in Golang?

  • Last Updated : 17 May, 2020

Golang supports time formatting and parsing via pattern-based layouts. In Go, the current time can be determined by using time.Now(), provided by the time package. Package time provides functionality for measuring and displaying the time.

To print Current date-time you need to import the “time” package in your Go program to work with date and time.

Example:




// Golang program to show
// the use of time.Now() Function
package main
  
import "fmt"
import "time"
  
func main() {
    dt := time.Now()
      
    // printing the time in string format
    fmt.Println("Current date and time is: ", dt.String())
}

Output :

Current date and time is:  2020-05-05 06:43:01.419199824 +0000 UTC m=+0.000076701

To print Specific date-time in Golang use format constants provided in the time package. The commonly used formats are:



const (
    ANSIC       = "Mon Jan _2 15:04:05 2006"
    UnixDate    = "Mon Jan _2 15:04:05 MST 2006"
    RubyDate    = "Mon Jan 02 15:04:05 -0700 2006"
    RFC822      = "02 Jan 06 15:04 MST"
    RFC822Z     = "02 Jan 06 15:04 -0700" // RFC822 with numeric zone
    RFC850      = "Monday, 02-Jan-06 15:04:05 MST"
    RFC1123     = "Mon, 02 Jan 2006 15:04:05 MST"
    RFC1123Z    = "Mon, 02 Jan 2006 15:04:05 -0700" // RFC1123 with numeric zone
    RFC3339     = "2006-01-02T15:04:05Z07:00"
    RFC3339Nano = "2006-01-02T15:04:05.999999999Z07:00"
    Kitchen     = "3:04PM"
    // Handy time stamps.
    Stamp      = "Jan _2 15:04:05"
    StampMilli = "Jan _2 15:04:05.000"
    StampMicro = "Jan _2 15:04:05.000000"
    StampNano  = "Jan _2 15:04:05.000000000"
)

Example:




// Golang program to print specific date and time
package main
  
import "fmt"
import "time"
  
func main() {
  
    dt := time.Now()
      
    // printing date and time in UnixDate format
    fmt.Println("Specific date and time is: ", dt.Format(time.UnixDate))
}

Output:

Specific date and time is:  Tue May  5 07:05:00 UTC 2020

Example:




// Golang program to print specific date and time
package main
  
import "fmt"
import "time"
  
func main() {
    dt := time.Now()
      
    // Format MM-DD-YYYY
    fmt.Println(dt.Format("01-02-2006"))
  
    // Format MM-DD-YYYY hh:mm:ss
    fmt.Println(dt.Format("01-02-2006 15:04:05"))
  
    // With short weekday (Mon)
    fmt.Println(dt.Format("01-02-2006 15:04:05 Mon"))
  
    // With weekday (Monday)
    fmt.Println(dt.Format("01-02-2006 15:04:05 Monday"))
  
    // Include micro seconds
    fmt.Println(dt.Format("01-02-2006 15:04:05.000000"))
}

Output:

11-10-2009
11-10-2009 23:00:00
11-10-2009 23:00:00 Tue
11-10-2009 23:00:00 Tuesday
11-10-2009 23:00:00.000000
