How can I replace a string within a URL by date?

It's taken me months to figure out how to show/hide certain content by days throughout the year, but now I'm stuck because the code gets too big for any browser to handle once I add every day for the entire year within the script.

Is there a way I can simply substitute each video's code for that day within just one embedded element? Trying to embed and then hide 371 videos is just too much.

The URL strings I'd need to swap out each day look like this:
5BZsAW78ch8
jEyvsHcQcLw
fBHx90y2QFo
_JMkjM4THd4
v2kh3s8RgYw
uhrrTXo1uRo

And the iframe code is like this:

<iframe width="560" height="315" src="https://www.youtube.com/embed/v2kh3s8RgYw" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

The working code (for just 3 days) is as follows:

<script src="https://code.jquery.com/jquery-1.12.0.js"></script>

<div align="center" style="margin:50px;">
<div class="show"></div>
<div class="vid5"><iframe width="560" height="315" src="https://www.youtube.com/embed/v2kh3s8RgYw" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe></div>
<div class="vid6"><iframe width="560" height="315" src="https://www.youtube.com/embed/uhrrTXo1uRo" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe></div>
<div class="vid7"><iframe width="560" height="315" src="https://www.youtube.com/embed/" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe></div>


</div>

<script>
function show_hide_me () {
  var myDate = new Date();
  var hour = myDate.getHours();
  var date = myDate.getDate();
  var month = myDate.getMonth();
  var minute = myDate.getMinutes()
if (month == 8 && date > 0 && date < 2){$('.vid5').show();$('.show').hide();} else {$('.vid5').hide();$('.show').show();}
if (month == 8 && date > 1 && date < 3){$('.vid6').show();$('.show').hide();} else {$('.vid6').hide();$('.show').show();}
if (month == 8 && date > 2 && date < 4){$('.vid7').show();$('.show').hide();} else {$('.vid7').hide();$('.show').show();}

 }
show_hide_me();
</script>
