You can sniff the browser's languages and based on that automatically switch that local. Best to do this in Application_BeginRequest of each request.

You'll probably want to be careful not to actually support all languages for translation (UICulture), but you might want to support all the culture information (Culture) for date and number formats.

You can also override specific settings explicitly by creating a new Culture object for a specific locale and hten overriding any values. For example, I like to override the currency symbol and set it to a $ because I only sell stuff in US dollars regardless of the user's culture. Yet I allow people to see dates and
numbers in their culture specific formats.

I have a related blog post that discusses selecting cultures and overriding some values (I typically override the currency symbol because I charge in $ regardless of locale).

All that said, for dates I much prefer NOT using numbers but using things Oct 10, 2015 or things like Yesterday, last week etc. These things are usually much better at showing the values wihtout the positioning ambiguity. Something to consider.
