Hi @qcjacques and @DaniCal
You can change the English name of month to Norwegian on the calendar block with the help of below code.
<script>
let en2nor = {
January: "Januar",
February: "Februar",
March: "Mars",
April: "April",
May: "Mai",
June: "Juni",
July: "Juli",
August: "August",
September: "September",
October: "Oktober",
November: "November",
December: "Desember",
},
$target = $(".calendar-block h1 > div"),
month = $target.text().split(" ")[0];
$target.text($target.text().replace(month, en2nor[month]));
</script>
You need to put this code in the Code Injection FOOTER under Settings > Advanced.
Please note that it requires jQuery. Since it was already added to the reference website, you can skip the next step.
Add jQuery to your website by adding below code in the Code Injection HEADER under Settings > Advanced.
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
PS: This is my first attempt to answer a question here. I hope this helps 🙂
