ARTICLES RELATED TO ISO 8601 - Times | | | |  ISO 8601 - Times: Encyclopedia II - ISO 8601 - TimesISO 8601 uses the 24-hour clock system that is used by much of the world. The basic format is hhmmss and the extended format is hh:mm:ss. hh refers to an hour between 00 and 24, where 24 is only used to notate the midnight at the end of a calendar date. mm refers to a minute between 00 and 59. ss refers to a second between 00 and 59 (or 60 in the exceptional case of an added leap second). So a time might appear as 13:47:30, or 134730.
It is also acceptable to omit elements to reduce precision. hh:mm, hhm ...

| | | | ISO 8601 - Times: Encyclopedia II - ISO 8601 - Dates The standard uses the Gregorian calendar, already the de facto standard of international trade. The standard acknowledges that other calendars may be used, such as the Julian calendar used by astronomers. It suggests that senders and receivers should explicitly agree when another calendar is used with the standard's notation. Dates are otherwise assumed to be Gregorian. In principle, dates should usually be converted to the proleptic Gregorian cal ...

| | | | ISO 8601 - Times: Encyclopedia II - ISO 8601 - Time interval Time intervals specify an amount of time. They may be specified in four ways:
Start and end, such as 2002-03-01T13:00:00Z/2003-05-11T15:30:00Z
Start and duration, such as 2002-03-01T13:00:00Z/P1Y2M10DT2H30M
Duration and end, such as P1Y2M10DT2H30M/2003-05-11T15:30:00Z
Duration only, such as P1Y2M10DT2H30M
Of these, the first three require two separate values, separated by the interval designator, which is usually a forward slash "/". (The double h ...

| | | | ISO 8601 - Times: Encyclopedia II - ISO 8601 - Duration Durations are represented by the format PnYnMnDTnHnMnS (nM may be replaced with nW to use the week format.) In this representation replace n with the appropriate number for the element that follows it (leading zeros are optional but may clarify ambiguous durations) The capital letters (P, Y, M, W, D, T, H, M, and S) are used as they are and not replaced. Thus P3Y6M4DT12H30M0S defines "a period of three years, six months, four days, twelve hours, thirty minutes, and zero seconds". Elements m ...

| | | | ISO 8601 - Times: Encyclopedia II - ISO 8601 - Combined representations Combining date and time representations is quite simple. It is in the format of <date>T<time>. The <date> and <time> sections are any proper representation of the date and time created by following the standard. A common use could be YYYY-MM-DDThh:mm:ss±hh:mm. 1981-04-05T14:30:30-05:00, for example.
The standard allows the replacement of T with a space if no misunderstanding arises. This is commonly done for human communications. A date/time with timezone like 1981-04-05T14:30-05 woul ...

| | | | ISO 8601 - Times: Encyclopedia II - ISO 8601 - General principles Dates and times are self-contained, and do not rely on any external context for their values. They are entirely numerical in representation, although certain specialized formats use roman letters to label fields. Every ISO date has exactly one possible unambiguous interpretation. These properties allow them to be truly international, without reliance on regional conventions, such as the names of the days of the week.
Dates and times are organized from most to least significant digits. Each value (eg, year, month, day, ti ...
