GO Parsing Custom Time

Question

Im trying to parse date with custom format- ddmmmyyyy. for example:

15may1997
dd 15 
mmm may 
yyyy 1997

This is my code:

const customFormat = "02jan2006"
t, err := time.Parse(customFormat, "15may1997")
if err != nil {
    fmt.Println(err)
}

And this is the output:

parsing time "15may1997" as "02jan2006": cannot parse "may1997" as "jan"

The parsing succeed only when changing the day:

t, err := time.Parse(customFormat, "15jan2006")

I have tried to read this and this and more articles, but couldn't figure out how to custom to my format.

What am I doing wrong here?

Thanks.

Golang time.Parse parses a formatted string on the basis of layout and returns the time value it represents.The layout which defines the format is Case-sensitive and has fixed predefined values.

So you need to update customFormat = "02jan2006" to "02Jan2006"

Below is the list of Case-sensitive Placeholders for different parts of the datetime.
