What is the formula for using a birthdate and creating a field to show current age today?

Hi @Kimberly_Zenyuch


It’s this:


DATETIME_DIFF(TODAY(),{Birth Date},‘years’)


Hope this helps.


I am getting error.Can you comment

DATETIME_DIFF(TODAY(),{DOB},‘years’)

It. says Sorry, there was a problem saving this field. Invalid formula. Please check your formula text.

@Sajeev_Wagle


DATETIME_DIFF(TODAY(), {DOB}, 'years')

I’m guessing you copy-pasted from @Julian_Kirkness‘s post - Airtable doesn’t like “smart quotes”. Above is the same formula with “dumb quotes” so it’s copy-paste safe.

I just copied the template but i am sure i used single quotes as i typed manually.Its a direct paste from formula bar. I couldnt upload my spreedsheet or screenshot.

Can someone advise where I input such a formula when using the iOS mobile app? I’m starting from scratch and never done anything with formula before.


I also have a DOB field and want to add an age field based on DOB. Any help would be appreciated.
