Datepickers are one of my least favorite interfaces, and I've written them in vanilla ja, Angular, and React and it never gets better. They have a ton of globalization and accessibility issues that will bite you. One of the big ones? Use of color to identity date classes. #a11y

Old school response from a salt and pepper white chin hair gal but server-side tech maybe? #JustThrowingSpaghetti

Dates and numbers are two of the most troublesome data types for internationalization. There are a couple front-end input methods that are configurable and accessible, but when you tie a calendar control to them it becomes 10x harder.

Makes sense. But impressive projects clearly are a strength for you. BBC for sure has had to manage massive amounts of data, large internationalization with accessibility and dates and numbers. I wonder if there's a resource there? Working with clashes in the tech itself? Yikes!

There are ways to do it, and I devote a fair amount of space to it in my book, but there's a lot to consider for something that's of questionable benefit other than it looks pretty and everyone has one.
