This project uses a script to look at the day of the week, current month, and current date. Then shows a div that matches that day, month, or date. Make the parent div have an id of "days", "months", and "dates". These ids can be whatever you like as long as the scripts are adjusted to match.
Place this styling in the Inside Head Tag custom code page settings.
<style>
#days > div {display: none;}
#months > div {display: none;}
#dates > div {display: none;}
</style>
Place this script in the Before /Body Tag custom code page settings.
<script>
$('#days > div').eq(new Date().getDay()).show();
$('#months > div').eq(new Date().getMonth()).show();
$('#dates > div').eq(new Date().getDate()).show();
</script>
Feel free to use this code in your own project. First design the element the way you want it and then add the code.
