You return a tuple.

You can access the components of a tuple with subscription
syntax: "tuple[i]".

As Andreas suggested, you can bind values to names with
"dtml-let" and reuse them several times.

  <dtml-let
    date="splitDate(...)"
    y="date[0]"
    m="date[1]"
    d="date[2]"
  >
  ....
  </dtml-let>

It may be easier to return a dictionary and use

  <dtml-with "splitDate(...)" mapping>
    <dtml-var y>
  </dtml-with>
