ISO 8601 should however be used to replace notations such as “2/4/95” and “9.30 p.m.”.Apart from the recommended primary standard notation YYYY-MM-DD, ISO 8601 also specifies a number of alternative formats for use in applications with special requirements.For example, the 53 weeks of the worst case year 1976 started with 1975-12-29 = 1976-W01-1 and ended with 1977-01-02 = 1976-W53-7.
Advantages of the ISO 8601 standard date notation compared to other commonly used variants: As dates will look a little bit strange anyway starting with 2000-01-01 (e.g.
like 1/1/0), it has been suggested that the year 2000 is an excellent opportunity to change to the standard date notation.
ISO 8601 is only specifying numeric notations and does not cover dates and times where words are used in the representation.
A week starts with Monday (day 1) and ends with Sunday (day 7).
For example, the first week of the year 1997 lasts from 1996-12-30 to 1997-01-05 and can be written in standard notation as for applications like industrial planning where many things like shift rotations are organized per week and knowing the week number and the day of the week is more handy than knowing the day of the month.
The international standard date notation is where YYYY is the year in the usual Gregorian calendar, MM is the month of the year between 01 (January) and 12 (December), and DD is the day of the month between 01 and 31.
