I want to have cal. pop-up select to start/default to a date OTHER THAN sys. date for specific node (edit) type.

Situation - D5.3, PHP 5.2.3, jstools, jscalendar 5.x-0.8 on social site with most users having birth date within 2 - 3 year span @ 28 years ago.

Profile type node with "birthday" field (CCK Date field w/ jscal pop-up active) has pop-up defaulting to today's (sys) date which requires all users to jump back @ 28 yrs. Would like to set start/default date to 07/01/1980, so that users can more easily navigate to their correct birth date. HOWEVER, this "overridden" default date should ONLY be for this node type (using events also, so would want sys date to default for those).

Thanks in advance to anyone shedding some light on my problem.
