How to Create a Favicon That Changes Automatically

I found this Free Favicon Maker the other day. It’s a nice tool to make a favicon (true to its name), but unlike other favicon generators, this one lets you create one from scratch starting with a character or an emoji. Naturally, I was curious to look at the code to see how it works and, while I did, it got me thinking in different directions. I was reminded of something I read that says it is possible to dynamically change the favicon of a website. That’s actually what some websites use as a sort of notification for users: change the favicon to a red dot or some other indicator that communicates something is happening or has changed on the page. I started browsing the emojis via emojipedia.org for inspiration and that’s when it struck: why not show the time with a clock emoji (🕛) and other related favicons? The idea is to check the time every minute and set the favicon with the corresponding clock emoji indicating the current time.
