Assign a number value to a Date in Excel

[samwong]

Hi

How should I use IF or IFS function to deal with the situation below. Many thanks!

I would to assign the number "1" for the age group of 1960s, "2" for the 1970s and "3" for the 1980s.

Current data:

Date	Age Group
1/1/1960
31/12/1969
1/1/1970
31/12/1979
1/1/1980
31/12/1989

<tbody>
</tbody>

Proposed result:

Date	Age Group
1/1/1960	1
31/12/1969	1
1/1/1970	2
31/12/1979	2
1/1/1980	3
31/12/1989	3

<tbody>
</tbody>
