How to convert a string to a time in Golang
Shubham Singh KshatriyaOverview
A string can be converted to a time in Golang using the Parse function within the time package.
Syntax
time.Parse(format, dateString)
Parameters
The Parse function accepts the following parameters:
format: The format in which the time (output) should be. For exampleDD-MM-YYYY.dateString: The string that needs to be converted to time.
Return value
The Parse function will return a Golang time object.
Example
In the following code, we will convert a string to time using the Parse function:
package main
import (
"fmt"
"time"
)
func main() {
dateString := "2021-11-22"
date, error := time.Parse("2006-01-02", dateString)
if error != nil {
fmt.Println(error)
return
}
fmt.Printf("Type of dateString: %T\n", dateString)
fmt.Printf("Type of date: %T\n", date)
fmt.Println()
fmt.Printf("Value of dateString: %v\n", dateString)
fmt.Printf("Value of date: %v", date)
}
Explanation
-
In lines 3-6, we have imported the necessary packages.
-
Inside the main() function, we have declared a string
dateStringand initialized it with2021-11-22in line #9. -
In line #10, we then converted the string to date using the
time.Parse()function by passing two parameters; theformatand thedateString. -
If there occurs some error while conversion, we output it on the console (line 13).
-
If there are no errors, we output the type and value of
dateStringanddaterespectively on the console (line17-21).
