+Instead of a constant, you can also pass any callable::
+
+    >>> import datetime
+    >>> class DateForm(forms.Form):
+    ...     day = forms.DateField(initial=datetime.date.today)
+    >>> print DateForm()
+    <tr><th>Day:</th><td><input type="text" name="day" value="12/23/2008" /><td></tr>
+
+The callable will be evaluted only when the unbound form is displayed, not when it is defined.
