Age calculation based upon date of birth and date of death in years, months and days.

[Ashley Akers]

I'm so sorry if I am asking for the 100th time, but i've searched so many posts and not seeing exactly what I need.  I work for a funeral home and we are now typing our arrangement information instead of hand writing them.  For our obituaries we always have to calculate the final age in years, months and days.  I thought if I could do a script to calculate it for me, it would save some time!  But, I know nothing about scripts in adobe.  Can somebody help me with the code?  My document will have the date of birth field and the date of death field, now I just need to have it calculate in years, months, and days in my age field.  PLEASE HELP!

[George_Johnson]

What date format will you be using for both date fields? For example, "dd/mm/yyyy".

[Ashley Akers]

I am using dd/mm/yyyy.  If it makes it easier, I can split the years, months and days into 3 different sections on the form.

This might seem like a simple calculation, but it's not. Is it really necessary to show the exact number of days, months and years? Why not just an age in years?

[Ashley Akers]

Yes, it is necessary.  We go to websites that have these calculators currently, but trying to save an extra step.

OK, what's the correct result for DOB "31/03/1980" and DOD "01/01/2021"?

Hi,
I already did something like that some years ago.
Here I've just translated my file.
for DOB "31/03/1980" and DOD "01/01/2021" I find 39 Years, 10 Months and 1 day.
Is it correct for you??

[Ashley Akers]

YES, that is exactly what I need!!  Can you give me that script?

[Bernd Alheit]

The script is in the PDF file.

[Asim123]

That script is not accurate.

[bebarth]

How can we have a calculation more accurate with a number of days different in accordance with the month???

[Asim123]

If you enter DOB 05/06/2001 and DOD 01/07/2021 you will get 20y 1m and 26days and  result should be 20y 0m and 26days so it's off by 1month.

[Ashley Akers]

Thank you!  I was able to get that script to work, but it is off by a day, possibly to account for leap years?  How can we account for this in the script? 

[Ashley Akers]

Actually, it is a month off.  If I calculate it with the DOB of 7/6/1927 and the date of death as 6/6/2021, it shows me 94 years and 30 days.  It is actually 93 years and eleven months.

No, @bebarth, that calculation isn’t correct as far as I can see. I’m using this site: Date Duration Calculator: Days Between Dates (timeanddate.com).

• From and including: Monday, March 31, 1980
• To and including: Friday, January 1, 2021
• Result: 14,887 days
• It is 14,887 days from the start date to the end date, end date included.
• Or 40 years, 9 months, 2 days including the end date.
• Or 489 months, 2 days including the end date.

@Ashley Akers, have you tried asking a site like this if you can license or purchase a copy of their calculation script (is it javascript?) and then running that script inside Acrobat? Is it the different number of days in each month that makes it too difficult for Acrobat's calculation methods? Is it a custom validation script you need? Which field property would you use?

[bebarth]

Hi,

I've just corrected the script.

Let me know if you find any other mistakes.

I'm not sure we have to count the day of the death...

@+

[Ashley Akers]

It is still off a month.

[Ashley Akers]

@bebarthIf I change even the day to reflect one day different, it will change it on the calculation a month versus a day.

[bebarth]

I restarted writing the script from the beginning with the clear ideas of the morning and here is the result.
I did several tests with different dates and all were correct.
Let me know if you still find any mistakes.
I remind you the dates are in format "dd/mm/yyyy".

[Ashley Akers]

Thank you!!  Now, how can I change things in order to put the month first versus typing the day?

[bebarth · Accepted solution]

You have to change:
...
if (util.scand("mm/dd/yyyy",this.getField("Deathday").valueAsString)>=util.scand("mm/dd/yyyy",this.getField("Birthday").valueAsString)) {
...
var DoB=parseInt(birthday[1]);
var MoB=parseInt(birthday[0]);
...
var DoD=parseInt(deathday[1]);
var MoD=parseInt(deathday[0]);
...
That's all for the script.
You also have to change the format of both date fields. Remove the script before changing them, else you will have the alert message!!!

This worked perfectly!  I can't ever thank you enough for your help!

[Ashley Akers]

@bebarthI have another issue with this.  This file that I created to calculate this goes on a couple of computers with adobe reader and not acrobat.  On one computer the file works fine, but the other one, which is a macbook, won't calculate the age but puts in "NaN" in the field.  How can I fix this?  Thanks!

[try67]

"NaN" stands for "Not a Number", which means they entered the date in a wrong format, or added some additional text to it, which they shouldn't have.

I am a newbie to Java script and adobe pro. I am working a PDF form to calculate time in years, months, and days between an upcoming appointment date (ApptDate)  and three other dates in the past (LVDate, DOIDate, and SxDate) I tried using the PDF provided above. When I download the file works, but if I change the name fileds it stops calculating the years, moths, and days. I am not even sure where I should be adding the script. Any help woudl be appreciated.
