Typing and parsing of any date format

[dave-stan]

On the pickadate home page, there is a link to Codepen which includes an example of the use of date.js to extend pickadate.js (from 2013) to enable the user to type in a date if they prefer, parse the date and then pass this through in mysql format; but the link is quite old https://www.datejs.com/ is no more and it uses an early version of pickadate.js
Is there an up-to-date version of this that works please? I've got clients who hate using a mouse and find it quicker to type things in directly.
