I think the most widely recognized, easily parseable format is the ISO-8601 version with the hyphens, 2023-09-21, which conveniently extends to including times as well. And it’s easy to convert to TW date format. In JS:
const d = new Date()
console.log(d.toISOString()) //=> 2023-09-21T16:35:48.771Z
console.log(d.toISOString().slice(0, 10)) //=> 2023-09-21
console.log(d.toISOString().replace(/\D/g, '')) //=> 20230921163612589
