Date Question on EHAS Form

I have read that when entering the date of your arrival that the date has to be entered as - Day, Month, Year. This may sound like a stupid question but when entering your Passport and Birth date do we enter "our" way or Day, Month, Year? I haven't seen [or can't find] any mention of this. We have a couple going down to use our timeshare this coming Saturday and I want to clarify it for them. They haven't traveled out of the country so I want to help make the process as easy as possible. Also need to know this info for us towards the end of the month.

Thanks in advance for your help.

Day, Month, year. Same as passport.

SXM uses the European date format. Day is first.

As does the majority of the rest of the world!!! mmddyy is mainly an American thing

Thank you....appreciate it.
