What would be the formula to show the age of a person as of today? I need the result in years

[Sandra_McCann]

DATETIME_DIFF([date1], [date2], ‘units’)

I saw this formula but how do I modify it to include my fields and a result in years for the units?

Maybe there’s something wrong with the data in your Birthday field or there is no information in that field, yet.

[W_Vann_Hall]

Check to make sure the single quotes around 'years' are straight single quotes ('') and not ‘pretty’ matching inverted comma-style single quotes (‘’). Sometimes when you copy-and-paste from the forum, you inadvertently pick up the latter, which will cause an error. Simply overwrite them using the single-quote key on your keyboard.

Good thoughts, this fixed it for me!

Here’s my final formula:

DATETIME_DIFF(TODAY(),Birthday, ‘years’)

Thanks for your response to the “Age” question.

How about instead of Years and Months, you want Years and a Decimal Equivalent for months.

For example exactly 12 years 6 months would simply be 12.5 years old. How to do that .5 calculation within the formula?

Thanks

To build upon @Matt_Bush’s example, try

IF(birthday,
    DATETIME_DIFF(
        TODAY(),
        birthday,
        'years')&
            RIGHT(
                ROUND(
                    MOD(
                        DATETIME_DIFF(
                            TODAY(),
                            birthday,
                            'days'
                            ),
                        365
                        )/365,
                    1
                    )&'',
                2
                )

That gives you YY.M.

I changed birthday to {Birthdate} and used your example, but it failed.
Birthdate is my Field Name

See below:
IF({Birthdate}, DATETIME_DIFF(TODAY(),{Birthdate}, ‘years’) & RIGHT(ROUND(MOD(DATETIME_DIFF(TODAY(),{Birthdate},‘days’), 365)/365, 1) &’’, 2)

[W_Vann_Hall]

Oops, I must’ve dropped a parenthesis between testing the routine and formatting it to post.
Try this:

IF(
    {Birthdate},
    DATETIME_DIFF(
        TODAY(),
        {Birthdate},
        'years'
        )&RIGHT(
            ROUND(
                MOD(
                    DATETIME_DIFF(
                        TODAY(),
                        {Birthdate},
                        'days'
                        ),
                    365
                    )/365,
                1
                )&'',
                2
            )
    )

Works PERFECTLY! Thanks Tim!

[Junko_Ohara]

I used this formula
=TONOW({DOB}, ‘years’)

[Khatia_Odzelash]

None of the options worked for me! I get the error sign. :frowning:
