# Conditionnal date calculating

I'm using Acrobat X Pro and looking for a date calculation script based on text fields. I'm really new at this but I can't seem to find a way.

My fields:
day1 (date of an event in yyyymmdd format, always filled)
day2 (date of a possible event in yyyymmdd format, can be left blank)
day3 (Result of the calculation)

Now what I want is:

If day2 is left blank, then day3 = day1 + 7 days
If day2 is filled, then day3 = day2 + 6 months

My Product Information:
Acrobat Pro 10.1, Windows

The way I see it would be to copy the same "onblur" script in both day1 and day2 as in:

day1 -> if day2 is blank
day3 = day1 + 7 days
else
day3 = day2 + 6 months

day2 -> if day2 is blank
day3 = day1 + 7 days
else
day3 = day2 + 6 months

Is there any easier method? What would the correct synthax be keeping the yyyymmdd format?

you should be able to just place the code into the Calculation script for day 3

if (day2 == "")
{
event.value = day1 + 7 days
}
else
{
event.value = day2 + 6 months
}

the easiest way to do math with dates is to get them down to the millisecond level by converting them to date objects like so---

var d1 = util.scand("yyyymmdd", getField("day1").value)

//now d1.valueOf() is the d1 date in milliseconds

var sevendays = 1000 * 60 * 60 * 24 * 7;

var x1 = d1.valueOf() + sevendays;

event.value = util.printd("yyyymmdd", x1);

@mmazal, your code will not work because x1 is not a Date object, just a number.

try67 is right

event.value = util.printd("yyyymmdd", new Date(x1));

another problem in my example seems to be that scand doesn't like the format yyyymmdd

it seems to be okay with yyyy-mm-dd

sorry for not being more helpful

"yyyymmdd" should work just fine, as long as you're using a valid Date object.
