Your browser is misconfigured. The site uses the YMD "standard" but your computer is configured with a locale that prefers US style for date inputs.

   <input type="date" placeholder="YYYY-MM-DD" class="input" required>

This site is only using mm/dd/yyyy for the generator input, the standard itself is not. The actual format in the security.txt file looks like:

Expires: Tue, 16 Mar 2021 05:09 -0400

Maybe slow down, read the spec, and proofread your comment for obvious errors before trying to troll for no reason.

If this is intended to be some kind of standard, it should follow other standards. I understand that this is "only" in the generator, but why even there?

It’s just using the standard date input. Formatting of the input UI will depend on browser, OS, and locale of the users device.

Ahhhh! Thanks for the update - I stand corrected.

I am French and my Chrome is set to US English. I just opened a FF session, switched to French and the input is dd/mm/yyyy.

I still think iso standard would be better: https://github.com/securitytxt/securitytxt.org/issues/72

Has the generator been updated? For me (UK) it's localised to dd/mm/yyyy, as I would expect in my region.

I like that the spec uses a universal and unambiguous format. I especially like that this generator is localised to my region though.

No, as @madeofpalk mentioned in response to my comment, it is using the standard date input. What you actually see depends on the locale of the browser (I see mm/dd/yyy in Chrome set to US English, and dd/mm/yyyy on FF set to French)
