Google Analytics

Hello,
I would like to add this Google Analytics code to my header.php. Where in the header can I put it? Just before the tag </head>
Thanks Nora

THis is the code:
<!– Global site tag (gtag.js) – Google Analytics –>

<script async src=”https://www.googletagmanager.com/gtag/js?id=UA-143592412-1″></script&gt;

<script>

window.dataLayer = window.dataLayer || [];

function gtag(){dataLayer.push(arguments);}

gtag(‘js’, new Date());

gtag(‘config’, ‘UA-143592412-1’);

</script>
