Date Formats

This script helps you format your dates in a variety of ways. These functions, which convert month and date numbers into strings, each use the function doIndex(), which addresses a string as if it were an array.

//------------------STRING-ARRAY UTILITY-------------------

// Find the substring at index n, counting 0 to n
function doIndex(aString, n)
{
    
    var str=""+aString
    
    // Count until the correct index
    for(var i = 0; i < n; i++)
    {
        var where = str.indexOf(':', 1)
        str = str.substring(where+1, str.length)
    }

    // Lop off the end of the string
    return str.substring(0, str.indexOf(':'))
}

// --------------------DATE STRING UTILITIES---------------------

// Return the 3-letter symbol for month #n
function month(n)
{
    var m = "Jan:Feb:Mar:Apr:May:Jun:Jul:Aug:Sep:Oct:Nov:Dec:"
    return doIndex(m, n)
}
