You will need to use a little HTML code. In this example, I'm using H1 to center it, but you can use any style you prefer.

Here's what to insert in your markdown file:

`

<script language = "JavaScript"> var now = new Date(); var dayNames = new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"); var monNames = new Array("January","February","March","April","May","June","July","August","September","October","November","December"); document.write("Today is " + dayNames[now.getDay()] + " " + monNames[now.getMonth()] + " " + now.getDate() + ", " + now.getFullYear()); </script> ¶

If you want to add the work week:¶

Today is

<script> Date.prototype.getWeek = function() { var onejan = new Date(this.getFullYear(), 0, 1); return Math.floor((((this - onejan) / 86400000) + onejan.getDay() + 1) / 7); } var weekNumber = (new Date()).getWeek(); var dayNames = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']; var now = new Date(); document.write(dayNames[now.getDay()] + " and we are in week " + weekNumber + "."); </script>
