How to Convert a YYYYMMDD String to a Date in Go?

Converting a YYYYMMDD String to a Valid Date in Go

Converting a string representing a date in the YYYYMMDD format to a valid date object in Go requires an understanding of the time package. This guide will cover the necessary steps and demonstrate how to work with date formatting and parsing in Go.

Using the Correct Format String

To convert a string in the YYYYMMDD format to a date, you need to use the time format string "20060102". This format specifies the order of year, month, and day components in the string.

Example Conversion

The following example demonstrates how to convert a YYYYMMDD string to a valid date:

<code class="go">package main

import (
    "fmt"
    "time"
)

func main() {
    dateString := "20101011" // YYYYMMDD format

    // Convert the string to a time object using Parse
    date, err := time.Parse("20060102", dateString)
    if err != nil {
        fmt.Println("Error parsing date string:", err)
        return
    }

    fmt.Println("Parsed date:", date) // Prints: 2010-10-11 00:00:00 +0000 UTC
}</code>

Format String for YYYY-MM-DD

If you want to convert a string in the YYYY-MM-DD format, you need to use the different format string "2006-01-02".

Example Output

Running the above example with "2010-10-11" as the input string will produce the following output:

Parsed date: 2010-10-11 00:00:00 +0000 UTC
