Age of individual

Hope someone can help me here!!

We have a field with the birthday of a person. We need to determine his age today! I am not sure of the calculation to use because of leap years and such.. any help would be greatly appreciated..

Thanks

Stuj,

There may be an easier solutions, but I quickly tested this and it worked.

1. Create a calculation field c_bday.

code:

---

Year(birthday_field)

2. Create a calculation field c_today. Use the 'Today' from the Date Functions menu and make sure the output of this field is TEXT.

3. Create a calculation field c_age. Use

code:

---

If(Left(bday_text, 5) <= Left(c_today, 5), Right(c_today,4) - Right(bday_text,4),Right(c_today,4) - Right(bday_text,4) - 1)

Hope this helps,

Tim

FileMaker.com has an article about this.

Click here.

Note: the article does caution the use of the Today function, but for some reason, doesn't mention Status(CurrentDate) as an alternative -- it's generally a much better way to go.

It may have been written before a version of FileMaker came out with Status functions.

The only real problem with the Today function is that is only evaluates when FileMaker opens the file, so if the file is left open overnight, Today won't return the correct date. Status( CurrentDate ) doesn't have this limitation. FileMaker has kept the Today function around for backwards compatibility.
