>if you're presenting to international audiences then either one of those two is unacceptable... I used to have all my domain names registered with Namecheap. I'd get emails from them saying things like '<whatever>.com is due to expire on 3/7/2018' --so, naturally, [being based in UK] I'd note on my calendar to renew the domain at the beginning of July, only to have it almost expire on me at the beginning of March. I emailed Namecheap several times about this, asking them to use less ambiguous dates in their reminder emails and, each time, got snotty replies saying "We are a US company and we use US date order" [which wouldn't have prevented them using something like "March 7 2018"] to which I pointed out that they had a global customer base, so should avoid expressing important data in formats which their oversees customers would mis-read. They refused to budge on this so, as each domain expired, I renewed it with another registrar instead and Namecheap lost all my business, my repeat business and my future business for ever. All because they were too damned stubborn to move away from using an ambiguous date format. Weird!
