Date and time notation

Date and time notation around the world varies.

An approach to harmonize the different notations is the ISO 8601 standard.

Since the Internet is a main enabler of communication between people with different date notation backgrounds, and software is used to facilitate the communication, RFC standards and a W3C tips and discussion paper were published.
