DATETIME_DIFF() - Mixing up the age of living and dead “people”? [SOLVED]
Hi there !
I’m very very new here, on Airtable, so to begin gently, I’ve come up with the idea to build a DB regrouping all the info I have on the pets I lived with (dead and alive).
But I’ve got a DATETIME_DIFF() formula difficulty.
On my base, I’ve created kind of a summary table with all the general info concerning the pets (Species, race, gender, etc…)
On this table, I’ve got a field Date of Birth (DoB) and a field Date of Death (DoD).
What I would like to do is to create a field that would give me the actual age of the pet (if still alive) or the age of the pet when it died, on same table, if possible :winking_face: .
Reading the help documentation and many topics here concerning the DATETIME_DIFF() formula I found this :
DATETIME_DIFF(TODAY(),{DoB},’years’)
Which works perfectly for the actual age of the living pet.
And…
DATETIME_DIFF({DoD},{DoB},’years’)
Which works perfectly for the age of the pet when it died.
If I get it right, I would need to create a IF() nested formula mixing both of these ones above, but after many tries I can’t find my way around this…
Could someone help me ?
Thanks a lot, in advance
(PS: Sorry for my English … It’s not my mother language :winking_face: )
(Yes, I was exactly aiming at this :winking_face: )
I think I may have forget one or 2 comma during my tries.
Anyway, thank you very very much for your help ! :thumbs_up:
I’ll play around with this one in my other bases
(That’s the best way to learn :winking_face: )
I just tried and that works perfectly !

I’m glad it worked out fine for you! :grinning_face_with_smiling_eyes:
Hhhmmm …
I’ve got another question though …
Is there a way to complete or adapt this formula…
IF(
{DoD}=Blank(),
DATETIME_DIFF(TODAY(),{DoB},’years’),
DATETIME_DIFF({DoD},{DoB},’years’)
)
… to get the results in “number of years / number of months” instead of only “number of years” ?
I’m pretty sure I’m missing something simple here but I can’t find what …
I must admit, I’m not very skilled yet to translate my thoughts into logical arguments, but it will come , I just need the right trigger :winking_face: .
Thanks a lot in advance again !

Add-on :
I tried to modify the ’years’ expression in the formula to get the results in “numbers of years / numbers of months” but I well, it simply didn’t work :roll_eyes: .
I thought about adding :
IF(DATETIME_DIFF(TODAY(),{DoB},’years’)<1,>something to get the age in months]
but I don’t know how to write the end of this and how to implement it :roll_eyes: …
At least, it helped me to think outside of the box , which helped me with a formula in another base I’ve created .
Concerning this particular formula, I’ve found the answer in another post :winking_face:
I don’t know if someone else would be interested in the formula I used, but just in case, I’ll leave it here :winking_face: (we never know :winking_face: )
I wasn’t sure if I needed to create a new topic as it concerns kind of a different problem I’m encountering.
But, it is linked to same DATETIME_DIFF formula, so I thought it was better to post here :winking_face: .
So, to summarize :
Few days ago, I was searching a DATETIME_DIFF formula that would get me the age of my actual living pets and the age of the ones who died.
I created 2 date fields in my pets table to that purpose :
Date of Birth > {DoB}
Date of Death > {DoD}
I asked for help and thanks to the Airtable Community my problem was solved !
BUT, I now got another problem in another DB with that exact same DATETIME_DIFF formula and I truly don’t understand why ,
So, the DB is meant to regroup all the quotes I like (coming from movies, TV Shows, books, songs, etc… ).
Because each quote (often) has an author, I created a table “Authors” where I can put all the informations I want concerning the authors (logical ) .
In that table I created, 2 date fields, identical to the ones in my pets table :
Date of Birth > {DoB}
Date of Death > {DoD}
The purpose is, again, to calculate the age of the author when he/she diedor the actual age of the author if he/she is still alive.
I thought that was a no brainer and copied/pasted (I tried to write it in the “formula box” too instead of copying/pasting it) the first formula that worked for my pets (before using the MOD() formula (see above :winking_face: )) :roll_eyes: :
IF(
{DoD}=Blank(),
DATETIME_DIFF(TODAY(),{DoB},’years’),
DATETIME_DIFF({DoD},{DoB},’years’)
)
But, it didn’t work this time :face_with_raised_eyebrow: (this is a screenshot of a “test Author table”)
Did I do something wrong ? :face_with_raised_eyebrow:
If yes, can someone explain me what ?
Because, as far as I understand the formula, the logic behind it, to me, seems to be the same … :face_with_raised_eyebrow:
Many thanks in advance

As far as I can tell there is a comma missing in the second line:
It now reads:
DATETIME_DIFF(TODAY(){DoB},‘years’),
but it should be:
DATETIME_DIFF(TODAY(),{DoB}, ‘years’),
That should solve it.

Ouch :grinning_face_with_sweat: ! My bad :grinning_face_with_sweat: !
I don’t know exactly how it happened :grinning_face_with_sweat: … But it happened :grinning_face_with_sweat: …
Correcting that missing comma mistake, I also found an “empty space” mistake (between 2 commas) re-writing that formula :grinning_face_with_sweat:
Thank you very much Sir ! :thumbs_up:
Everything works again
I’m sorry to ask again … But I’ve got a tiny question in addition
Still concerning my “Authors” table…
After correcting my mistakes, I modified a little bit my formula so when an author of a quote doesn’t have a date of birth, the result is “N/A”.
IF(
{DoB}=BLANK(),'N/A',
IF(
{DoD}=BLANK(),
DATETIME_DIFF(TODAY(),{DoB},'years'),
DATETIME_DIFF({DoD},{DoB},'years')
))
The formula works !
I just wanted to add “years” somewhere so when there is an age to calculate, I get something like “63 years”.
I’ve tried this :
IF(
{DoB}=BLANK(),'N/A',
IF(
{DoD}=BLANK(),
DATETIME_DIFF(TODAY(),{DoB},'years') & ' years ' &,
DATETIME_DIFF({DoD},{DoB},'years') & ' years ' &
))
And other placements of the “years” but I’m not able to find the right place in the formula, so it doesn’t work …
Maybe I’m just not writing the “years” right .
I have had several problems the past few days to add plain text in my formulas .
Thanks for the help in advance again

Try
IF(

IF(
{DoD}=BLANK(),
DATETIME_DIFF(TODAY(),{DoB},'years'),
DATETIME_DIFF({DoD},{DoB},'years')
)&' years'
)

Perfect ! :thumbs_up:
It works !
