Date strings are a pattern, and Regular Expressions will be the best approach. The date on your document will depend on your timezone and your writing preference, so this is just a template to help you customize according to your document or writing requirements.

To replace dates: Find all dates in your document in the form of:

Region/Timezone	use the expression
(US) --- month/day/year	(\d*)/\d*/(\d{4})
(Europe, Africa) --- day/month/year	\d*/(\d*)/(\d{4})
(Asia, Hungary) --- year/month/day	(\d{4})/(\d*)/\d*

The separator (oblique stroke or slash) can also be changed
