Closing this one for now based on the discussion in #7761!

Although we haven't talked specifically about dayjs in #7761, I think the dayjs change is potentially OK. As a dev-only dependency it'd mainly be to make npm installs for contributors a little faster I think?

[ksen0]

@davepagurek dayjs is tiny not that small*, but it has tests and locale features and so on. I think it's potentially needlessly brittle to introduce a hardcoded array of months (it would be easily possible for a contributor to cause accidental and very hard to spot regression). If we get rid of this dependency, why not use new Intl.DateTimeFormat('en-US', { month: 'long', day: 'numeric', year: 'numeric' }).format(new Date()) or something else built in for the banner?

*you're right, I apologize, it's noticeably sized, I misread original issue text!

[error-four-o-four]

Indeed, Intl.DateTimeFormat would be the better choice. It's widely supported and was introduced in es6 (regarding polyfills)

I'll update the PR
