Another option, of course, is =DATE(A3,A2,A1)

=A1 & "/" &A2 & "/" &A3 will give text, rather than a date, but =--(A1 &
"/" &A2 & "/" &A3) will give a date (if the cell is formatted
appropriately).
In some cases, if you try to do calculations based on the cell containing
text, it will translate it to a date in the calculation.

Hi everyone,

Is it the same when you type in 01/01/2000 as in a date format AND when
you
pick up three different numbers from three different cells and combine
them
using & sign? For ex, A1 & "/" &A2 & "/" &A3.

If after combining the three number, will Excel still look at the
combined
cell as a "date". I need to do some calculating with the combined cell,
and
I want Excel to look at it as a date, let's say I need to calculate the
age,
but the birth date need to be hidden. How can I do with this?

Thanks,
GU
