Go current time
last modified April 11, 2024
In this article we show how to display current date and time in Golang. The
time package provides functionality for measuring and displaying
time.
The Now function returns the current local time.
The Format function returns a textual representation of the time
value formatted according to layout. The layout is either a predefined constant
value or a specific format of the reference datetime: Mon Jan 2 15:04:05-0700 MST 2006.
$ go version go version go1.22.2 linux/amd64
We use Go version 1.22.2.
Go current time example
The following example print the current date and time.
package main
import (
"fmt"
"time"
)
func main() {
now := time.Now()
fmt.Println("The current datetime is:", now)
}
The example prints the current time with Now.
$ go run current_time.go The current datetime is: 2020-05-26 18:56:03.268250331 +0200 CEST m=+0.000060798
Go current time parts
In the following example, we print the parts of the current time.
package main
import (
"fmt"
"time"
)
func main() {
now := time.Now()
fmt.Println("Year:", now.Year())
fmt.Println("Month:", now.Month())
fmt.Println("Day:", now.Day())
fmt.Println("Hour:", now.Hour())
fmt.Println("Minute:", now.Minute())
fmt.Println("Second:", now.Second())
fmt.Println("Nanosecond:", now.Nanosecond())
}
In the code example, we print the year, month, day, hour, minute, second, and nanosecond with the corresponding functions separately.
$ go run current_time_parts.go Year: 2020 Month: May Day: 26 Hour: 19 Minute: 1 Second: 12 Nanosecond: 985372280
Go format current time
Go does not use the typical yyyy-mm-dd format specifier; it uses
the following reference datetime format:
Mon Jan 2 15:04:05 -0700 MST 2006
We format the time how we structure this specific reference datetime.
package main
import (
"fmt"
"time"
)
func main() {
now := time.Now()
fmt.Println("Time: ", now.Format("15:04:05"))
fmt.Println("Date:", now.Format("Jan 2, 2006"))
fmt.Println("Timestamp:", now.Format(time.Stamp))
fmt.Println("ANSIC:", now.Format(time.ANSIC))
fmt.Println("UnixDate:", now.Format(time.UnixDate))
fmt.Println("Kitchen:", now.Format(time.Kitchen))
}
The example displays the current time in custom and predefined formats.
fmt.Println("Date:", now.Format("Jan 2, 2006"))
This is an example of a custom datetime format.
fmt.Println("ANSIC:", now.Format(time.ANSIC))
This is an example of a predefined format.
$ go run current_time_format.go Time: 19:07:53 Date: May 26, 2020 Timestamp: May 26 19:07:53 ANSIC: Tue May 26 19:07:53 2020 UnixDate: Tue May 26 19:07:53 CEST 2020 Kitchen: 7:07PM
