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.
Pro-tip: when saving files on a computer type the date at the beginning of the file name as in year/month/day format, but without the "/" e.g. today would be 20230810. This makes the files automatically arrange in chronological order.
Pro-pro-tip: use the iso8601 standard: 2023-08-10. Why reinvent the wheel?
As i'm Hungarian, this is how everyone uses it here. Usually dots instead of dashes. It's a "pro" language.
ISO 8601 allows either dashes or no separator, both 20230810 an 2023-08-10 are valid, but not 2023.08.10 .
Without dashes is annoying to read though.
You can still use - in place of / for readability
2023-08-10_filename.ext is great for that
