Where: This change applies to Lightning Experience, Salesforce Classic, and all versions of the Salesforce app in all editions, except Database.com.
How: Review the changes to date, time, name, and currency formats for the locales that you use in Salesforce and evaluate how they affect you. Then test your filters, code, and components as needed.
