Problem solved.
I mistake during write code:
<script type="text/javascript">
$(function () {
var th = $('[title="Calendar"]').find('tr').eq(2).find('th');
$(th)[0].innerHTML = 'MonDay'; // SunDay
$(th)[1].innerHTML = 'TuesDay'; // MonDay
$(th)[2].innerHTML = 'WednesDay'; // TuesDay
$(th)[3].innerHTML = 'ThursDay'; // WednesDay
$(th)[4].innerHTML = 'FriDay'; // ThursDay
$(th)[5].innerHTML = 'SaturDay'; // Friday
$(th)[6].innerHTML = 'SunDay'; // Saturday
});
</script>
When I correct it’s worked.
<script type="text/javascript">
$(function () {
var th = $('[title="Calendar"]').find('tr').eq(2).find('th');
$(th)[0].innerHTML = 'SunDay'; // SunDay
$(th)[1].innerHTML = 'MonDay'; // SunDay
$(th)[2].innerHTML = 'TuesDay'; // MonDay
$(th)[3].innerHTML = 'WednesDay'; // TuesDay
$(th)[4].innerHTML = 'ThursDay'; // WednesDay
$(th)[5].innerHTML = 'FriDay'; // ThursDay
$(th)[6].innerHTML = 'SaturDay'; // Friday
});
</script>
