No such thing as a CSS class. HTML has classes, CSS has selectors

Well, you could do something like:
var cells = document.getElementsByTagName('td');
for (var i = 0; i < cells.length; i++) {
if (cells[i].className != 'event') {
var text = "n/a";
var textNode = document.createTextNode(text);
var span = document.createElement('span');
span.className = 'printOnly';
span.appendChild(textNode);
cells[i].appendChild(span);
}
}
but ...

Why isn't the lack of text content of the cells meaningful already? Or
is the sole indication that something is happening on a day the
stylesheet? (Hint optional presentation layers are not the ideal
place to put content).
