In portuguese people say "vinte de junho de dois mil e vinte dois", meaning "twenty of june of two thousand twenty two". The first few days of the month are ordinal: people say "primeiro de janeiro" meaning "first of january".

Japanese uses a neat system akin to YYYY-MM-DD. 2022-06-20 becomes ２０２１年６月２０日 meaning "2021 year 6 month 20 day". Really nice to read. Actual pronunciation is very irregular though, especially days of the month where about half of them are irregular.
