Repost from Reddit: https://www.reddit.com/r/dataisbeautiful/comments/8qt94a/endianess_of_date_and_address_formats_in_europe/

On the reddit comments some user wrote the address format for Russia is wrong on this map, they use big-endian as well.

Also Hungary is the only country in Europe where we use big endianness in names, aka Eastern name order: surname first, firstname second.
