This code dynamically changes the month on your website so you don't have to.
<script>
// Get the current month
var month = new Date().getMonth();
// Get the list of months
var months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
// Display the current month
document.getElementById("current-month").innerHTML = months[month]
</script>
This one's pretty simple to use. Just wrap whatever text element you're using in a <span></span> and then give it an ID of current-month.
Once you do that, the text that is wrapped in that span will display whatever the current month is.
