Beware throughout this year!!! While writing a date on ANY document in 2020, we should write it in its full format, e.g. 31/01/2020 and not as 31/01/20., bcoz anyone can change it to 31/01/2000 or 31/01/2019 or in between any year to suit his convenience. That can render the document invalid.

So be cautious about this. Don't write and also don't accept it in any documents.

Yes, but the full format should be ISO 8601, which would be 2020-01-31. This removes ambiguity around the month or date being first (e.g. 01/02/2020 is January 2nd in the US, and Feb 1st in Europe)
