The first edition of the ISO 8601 standard was published as ISO 8601:1988 in 1988. It unified and replaced a number of older ISO standards on various aspects of date and time notation: ISO 2014, ISO 2015, ISO 2711, ISO 3307, and ISO 4031. It has been superseded by a second edition ISO 8601:2000 in 2000, by a third edition ISO 8601:2004 published on...
Date and time values are ordered from the largest to smallest unit of time: year, month (or week), day, hour, minute, second, and fraction of second. The lexicographical order of the representation...Each date and time value has a fixed number of digits that must be padded with leading zeros.Representations can be done in one of two formats – a basic format with a minimal number of separators or an extended format with separators added to enhance human readability. The standard notes t...For reduced precision,any number of values may be dropped from any of the date and time representations, but in the order from the least to the most significant. For example, "2004-05" is a valid I...The standard uses the Gregorian calendar, which "serves as an international standard for civil use." ISO 8601:2004 fixes a reference calendar date to the Gregorian calendar of 20 May 1875 as the date the Convention du Mètre (Metre Convention) was signed in Paris(the explicit reference date was removed in ISO 8601-1:2019). However, ISO calendar date...
ISO 8601 uses the 24-hour clock system. As of ISO 8601-1:2019, the basic format is T[hh][mm][ss] and the extended formatis T[hh]:[mm]:[ss]. Earlier versions omitted the T (representing time) in both formats. 1. [hh] refers to a zero-padded hourbetween 00 and 24. 2. [mm] refers to a zero-padded minutebetween 00 and 59. 3. [ss] refers to a zero-padde...
A single point in time can be represented by concatenating a complete date expression, the letter "T" as a delimiter, and a valid time expression. For example, "2007-04-05T14:30". In ISO 8601:2004 it was permitted to omit the "T" character by mutual agreement as in "200704051430",but this provision was removed in ISO 8601-1:2019.Separating date and...
Durations define the amount of intervening time in a time interval and are represented by the format P[n]Y[n]M[n]DT[n]H[n]M[n]S or P[n]W as shown on the aside. In these representations, the [n] is replaced by the value for each of the date and time elements that follow the [n]. Leading zeros are not required, but the maximum number of digits for ea...
A time interval is the intervening time between two time points. The amount of intervening time is expressed by a duration (as described in the previous section). The two time points (start and end) are expressed by either a combined date and time representation or just a date representation. There are four ways to express a time interval: 1. Start...
ISO 8601:2000 allowed truncation (by agreement), where leading components of a date or time are omitted. Notably, this allowed two-digit years to be used as well as the ambiguous formats YY-MM-DD and YYMMDD. This provision was removed in ISO 8601:2004. The first and seventh examples given above omit the leading - for century. Other formats have one...
ISO 8601-2:2019 defines a set of standardised extensions to the ISO 8601 date and time formats. Extended Date/Time Format (EDTF) 1. The EDTF is given as an example of a profile of ISO 8601. Some of its features are: 1.1. Uncertainand approximate qualifiers, '?' and '~', as well as their combined used, '%'; they can be applied to the whole date or t...
On the Internet, the World Wide Web Consortium (W3C) uses the IETFstandard based on ISO 8601 in defining a profile of the standard that restricts the supported date and time formats to reduce the chance of error and the complexity of software. The very simple specification is based on a draft of the RFC 3339 mentioned below. ISO 8601 is referenced ...

Lunar eclipse. A lunar eclipse is an astronomical event that occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. [1] Such an alignment occurs during an eclipse season, approximately every six months, during the full moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit .
