In Korea, everything big comes first. It's year, month, and then the date. So for example, 1st of October, 2017 would be 17/10/1.
Same with addresses, it's country, city, and then the street name. In the rest of the world, it would be street name, city, and then country.
Same with names, it's last name first, and first name last. For example, Song Joongki (Song is his last name but comes first).
Hope it makes sense :).
