Calculate date + 30 days then first of following month

[r.armont]

I have a calculated field in my form that adds 30 days to a date entered into DateofHire. I need the resulting date to be the first of the following month.

Ex:

Using a hire date of 7/1/17 my script results in 7/31/17, I need to calculate it to 8/1/17.

If the hire date is 7/2/17, the script results in 8/1/17, I need the field to go to 9/1/17.

I hope that makes sense. Here's my current script:

// Custom Calculate script for NewDate field

(function () {

    // Get date entered into the DOH field

    var sDate = getField("DateofHire").valueAsString;

    // Convert string to date

    var d = util.scand("mm/dd/yyyy", sDate);

   // Add days to date

    d.setDate(d.getDate() + 30);

    // Populate this field with the result

    if (sDate) {

        event.value = util.printd("mm/dd/yyyy", d);

    } else {

        event.value = "";

    }

})();

Change this line:

d.setDate(d.getDate() + 30);

To:

d.setDate(d.getDate() + 30);
if (d.getMonth()==11) {
    d.setMonth(0);
    d.setFullYear(d.getFullYear()+1);
} else d.setMonth(d.getMonth()+1);
d.setDate(1);

I created a Date JavaScript library for just these sorts of things. You can read about it here...

The nextMonth method will allow you to advance the date to the first day of the next month and optionally set it to the first business day of that month assuming a Monday through Friday work week.
