Date formula

[coolkat999]

Hi

I need some help writing a formula.

I have a table showing dates of birth for employees. I want to be able to show a "yes" in the table if the employee reaches the minimum age in months under each of the years. So for example, the first employee with a dob of 1/2/1960 should only have Yes showing under the date range 1/1/2021 - 31/12/2021 as they will have met the minimum age requirement of 738 months.

However, I only need the "yes" to show once (ie the earliest possible occasion)

Could someone help me write the formula?

	From	01/01/2019	01/01/2020	01/01/2021	01/01/2022	01/01/2023
	To	31/12/2019	31/12/2020	31/12/2021	31/12/2022	31/12/2023
	Required age (months)	736	737	738	739	740
DOB	01/02/1960			Yes
	14/08/1958	Yes
	09/08/1964

<colgroup><col width="87" style="width: 65pt;"><col width="173" style="width: 130pt;"><col width="87" span="5" style="width: 65pt;"></colgroup><tbody>
</tbody>

Many thanks

Will

Hi,

Does this do what you need:

Book1
	A	B	C	D	E	F	G
1		From	1/1/2019	1/1/2020	1/1/2021	1/1/2022	1/1/2023
2		To	12/31/2019	12/31/2020	12/31/2021	12/31/2022	12/31/2023
3		Required age (months)	736	737	738	739	740
4	DOB	2/1/1960			Yes
5		8/14/1958	Yes
6		8/9/1964

Hi, I would use datedif formula (with 'from' in a1 and considering date difference in row 2 in months)
<b$3,countif($a4:a4,"yes")>

DATEDIF($A4,B$2,"m")

so in b4:

</b$3,countif($a4:a4,"yes")>
