When selecting a world, the Narrator will always say both the month and day of the week of the world's last played date in English, regardless of the language selected by the user.

For my most recent world, last played in 18/04/2019, the narrator says Thursday, Apr 18; for an older world, played in 19/12/2017, it says Tuesday, Dec 19. So, from what it looks like, the game is probably doing some sort of automated conversion to long date format, which does not take multiple languages into account.

The fix is to add separate strings for each month and day of the week, and "assemble" the long date format according to the language. It's also important to point out that different languages use different date formats, so, if implemented, these should be re-order-able through %s placeholders.

Steps to reproduce

1. Set your language to anything other than English.
2. Enable the Narrator.
3. Go the the world selection screen, and click a world.
   • Pay close attention after it says "Last played": before actually passing onto the time, it will say the day of the week and the month of the last played date in English.
