The International Standard date formats

In an effort to avoid miscommunication between people using the British date format and those using the American date format, an International Standard was developed. If an Australian writes December 15, 2019 as 15/12/2019, but an American writes the same date as 12/15/2019, who’s right? The international standard recommends writing the date as year, then month, then the day: YYYY-MM-DD. So if both the Australian and American used this, they would both write the date as 2019-12-15.

Writing the date this way avoids confusion by placing the year first. Much of Asia uses this form when writing the date. For example:

December 15, 2019 would be written as 2019 December 15. (Did you notice there’s no comma?).
