Calculating Age on a Given Date

[Philip_Barber]

I am a real novice at formulas and I have been unable to work out what I have done wrong. Can somebody please tell me.

DATETIME_DIFF(TODAY(01-11-2019),{DOB LInk},‘Y’)

I am trying to return the age of a person based on the difference between the DOB and the date in the future. What I have here works sometimes but sometimes gives the incorrect age. The problem occurs if the dob is later in the year than todays date.

Airtable

AYM Festival test 2019 - Airtable

Explore the "AYM Festival test 2019 " base on Airtable.

Hopefully the link will show that the first age (for Jacob) is correct but the second line for (Peter) is one year out.

As Justin said the answer was in the thread and provided something I could not do myself.
Best of luck with it.

Yes @Philip_Barber and @Justin_Barrett I tried pasting the formula in but it marked error. I do not need the date AS OF a specific date, or do I need to add a specific date?

for example what does DATE_TIME PARSE mean?

I used this example: DATETIME_DIFF(TODAY(11-18-2020),{DOB LInk},‘M’)/12

[Antonia_Lavende]

Yes I have. They are marking Error.

Hi Antonia,

I am not an expert and I relied on somebody else in the community answering my question and the formula that they gave me is …. DATETIME_DIFF(DATETIME_PARSE(‘11-11-2019’,‘DD-MM-YYYY’),{DOB LInk},'Y’)

In my case the child gave their specific DOB and this then calculated what their age would be on a specific date in the future.

I hopes this helps

I see two problems:

1. The ‘M’ string is using styled quotes. Airtable formulas only work with non-styled quotes. Notice the very subtle difference between ‘M’ and 'M'.
2. You added numbers inside the call to the TODAY() function. TODAY() doesn’t accept any arguments. Even if it did you can’t just type a date and have it interpreted as a date.

The correct formula should be:

DATETIME_DIFF(TODAY(), {DOB Link}, 'M') / 12
