I noticed that the aria-label on the day component outputs symbols.

Not sure if the problem is in moment(). It's something to do with the locale aware format LL

This works

const ARIAL_LABEL_TIME_FORMAT = 'dddd, MMMM DD, YYYY'; // Monday, May 09, 2022

But it's not locale aware I presume so it might need some further 👀
