the datebox calendar popup will default to today's date unless a date is already set in the datebox.

This zkfiddle shows a simple way, switching to a different year when the calendar popup opens on an empty datebox.

<zk xmlns:w="client">
    <script><![CDATA[
    zk.afterLoad('zul.db', function() {
        var xCalendarPop = {};
        zk.override(zul.db.CalendarPop.prototype, xCalendarPop, {
            open : function() {
                var db = this.parent;
                var oldDate = db.getValue();
                xCalendarPop.open.apply(this, arguments);
                if(db.defaultYear && !oldDate) {
                    var initialDate = this.getValue();
                    initialDate.setFullYear(db.defaultYear);
                    this.setValue(initialDate);
                }
            }
        });//zk.override
    });//zk.afterLoad
    ]]></script>
    <datebox w:defaultYear="2010"/>
</zk>
