Editing Calendar date (section)

===Gregorian, year–month–day (YMD) <span id="YMD date"></span>===
<!--[[YMD]] and [[YMD date]] redirect here-->
{{Redirect|YMD}}
In this format, the most significant data item is written before lesser data items i.e. the year before the month before the day. It is consistent with the [[Endianness|big-endianness]] of the [[Hindu–Arabic numeral system]], which progresses from the highest to the lowest order magnitude. That is, using this format textual orderings and chronological orderings are identical. This form is standard in East Asia, Iran, Lithuania, Hungary, and Sweden; and some other countries to a limited extent.

Examples for the 9th of November 2003:
*2003-11-09: the standard Internet date/time format,<ref>[http://www.w3.org/TR/NOTE-datetime W3C Date and Time Formats] Internet date/time format<!-- retrieved 23 September --></ref> a profile of the international standard [[ISO 8601]], orders the components of a date like this, and additionally uses leading zeros, for example, 1996-05-01, to be easily read and sorted by computers. It is used with [[UTC]] in RFC 3339. This format is also favored in certain [[Asia]]n countries, mainly [[East Asian]] countries, as well as in some European countries. The big-endian convention is also frequently used in [[Canada]], but all three conventions are used there (both endians and the American MMDDYYYY format are allowed on Canadian bank cheques provided that the layout of the cheque makes it clear which style is to be used).<ref>{{cite web|url=http://www.cdnpay.ca/news/new_cheque_specs.asp |title=Canadian Payments Association – Specifications for Imageable Cheques and Other Payment Items |url-status=dead |archive-date=6 July 2010 |archive-url=https://web.archive.org/web/20100706223651/http://www.cdnpay.ca/faqs/new_specifications.asp |date=February 3, 2009 |quote=Adoption of a numeric date field in one of three specified formats (YYYYMMDD, MMDDYYYY or DDMMYYYY.

* 2003 November 9
* 2003Nov9 or 2003Nov09
* 2003-Nov-9 or 2003-Nov-09
* 2003-Nov-9, Sunday
* 2003. {{sic|hide=y|no|vember}} 9. – The official format in [[Hungary]], point after year and day, month name with small initial. Following shorter formats also can be used: 2003. {{sic|hide=y|nov}}. 9., 2003. 11. 9., 2003. XI. 9.
* 2003.11.9 using [[Full stop|dots]] and no leading zeros, common in [[China]].
* 2003.11.09
* 2003/11/09 using [[slash (punctuation)|slash]]es and leading zeros, common in [[Japan]] on the Internet.
* 2003/11/9
* 03/11/09
* 20031109 : the "basic format" profile of ISO 8601, an 8-digit number providing [[monotonic]] date codes, common in computing and increasingly used in dated computer file names. It is used in the standard [[iCalendar]] file format defined in RFC 5545. A big advantage of the ISO 8601 "basic format" is that a simple textual sort is equivalent to a sort by date.

It is also extended through the universal big-endian format clock time: 2003 November 9, 18h 14m 12s, or 2003/11/9/18:14:12 or (ISO 8601) 2003-11-09T18:14:12.
