Rails 5 - Translation Missing in date_select Month Field

Scenario: You’ve used a date_select and everything was fine with the ‘en’ default locale. You’ve added a new locale like en-GB and now you see a strange thing in your dropdown:

Fix: We need to either manually populate the new translation file with the keys for month names like so

    month_names: [January, Febuary, March, April, May, June, July, August, September, October, November, December]
    abbr_month_names: [Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec]
    day_names: [Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday]

OR add a fallback to application.rb where we use the a default translation if we are missing the keys in our custom file.
