In CJK languages, dates are commonly written in year-month-day order.
For Chinese and Japanese, months are written as Arabic numerals followed by the character 月 (meaning "month"), unless you are writing something with a classic or traditional feel.
e.g., October 31, 2025 is 2025年 10月 31日 in Chinese and Japanese; similarly in Korean: 2025년 10월 31일.
So in short, there isn’t much difference from the ISO format. I highly suggest keeping the current form in at least CJK languages.
