Displaying dates in user format

When displaying dates from software, it's easy to confuse users if they don't know the format you are going to rely on.

We already know that time zones play an important role and that when displaying a time we always want to show it as time-zone-aware, but even dates can have their ambiguities. If you write 3/4/2018, will it be April 3^rd or March 4^th?

For this reason, you usually have two choices:

• Go for the international format (2018-04-03)
• Localize the date (April 3, 2018)

When possible, it's obviously better to be able to localize the date format, so that our users will see a value that they can easily recognize.
