For the version 7 of zk use:

<zk xmlns:w="client">
<style>
    .custom-selected-node {
        background-color: #99FF99 !important;
    }
</style>
<vlayout>
    <label value="selected dates" />
    <textbox rows="7" id="tbx" width="300px" />
</vlayout>
<calendar id="cal" use="test.custom.component.WeekPicker">
    <attribute w:name="_markCal"><![CDATA[
        function (opts) {
            // clear old custom-selected-node
            jq('.custom-selected-node').each(function () {
                jq(this).removeClass('custom-selected-node');
            });
            this.$_markCal(opts);
            if (this._view == 'day') {
                // target: current focused date (td)
                // parent: tr
                var target = jq('.z-calendar-selected')[0],
                    parent = target.parentNode,
                    node = parent.firstChild,
                    beforeCnt = 0,
                    found;
                // loop through each td
                while (node) {
                    // add selected style
                    jq(node).addClass('custom-selected-node');
                    if (node == target) {
                        found = true;
                    } else if (!found) {
