This post is about the default language of a new site in SharePoint Online. There are some pros and cons of using English as the default language for Non-English sites.

In my case I want to know what is better for Swedish users:

1. A site with English as default and Swedish as an alternate language (among many other alternate languages)?
2. A site with Swedish as default?

Today, when you create a site, English is pre-selected in the form, you have to choose Swedish actively. When you create a team, the underlying SharePoint Site will have English as the default language.

Recently I wanted to add Chuvash localization to the jQuery UI datepicker. Unfortunately, my pull request was rejected. The reason is that jQuery UI will be using Globalize framework: The jQuery Globalize framework relies on CLDR, so What is Unicode CLDR (Common Locale Data Repository)?

The Unicode CLDR provides key building blocks for software to support the world’s languages, with the largest and most extensive standard repository of locale data available. This data is used by a wide spectrum of companies for their software internationalization and localization, adapting software to the conventions of different languages for such common software tasks
