This template is used on approximately 53,000 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.

This template uses Lua:

{{Start date text}}, {{Birth date text}}, {{End date text}}, and {{Death date text}} are easy to read "plain text" date and time templates that emit microformat dates for events. These templates are an alternative to the {{Start date}}/{{Birth date}} and {{End date}}/{{Death date}} templates that also emit microformats but require dates to be expressed as numbers, with a parameter for the year, another for the month, and so on. "Fuzzy" dates and times are supported. For events where the precise time, day or month is not known, the user may omit these details. Time zones are assumed to be local to the event. If time zone information is specified, the otherwise optional timezone parameter must be set.

Julian calendar dates

Samples below demonstrate use of Julian calendar dates. Displays 9 June [O.S. 30 May] 1672 (1672-06-09), and emits hidden microformat date: 1672-06-09

{{Start date text|9 June 1672|{{OldStyleDate|9 June|1672|30 May}}}} → 9 June [O.S. 30 May] 1672

{{Birth date text|9 June 1672|{{OldStyleDate|9 June|1672|30 May}}}} → 9 June [O.S. 30 May] 1672

{{End date text|9 June 1672|{{OldStyleDate|9 June|1672|30 May}}}} → 9 June [O.S. 30 May] 1672

{{Death date text|9 June 1672|{{OldStyleDate|9 June|1672|30 May}}}} → 9 June [O.S. 30 May] 1672

Parameters

|1=: (required) The date and time to display and to emit as a microformat date. If year is absent, the current year is assumed. If day is missing, the first of the month is assumed. If hour, or minutes are missing, zero is assumed. If time zone or location is missing, the local time of the event discussed in the article is assumed. See timezone parameter if UTC time is desired. Authors may specify place names (see list) or time zones such as EDT, PST, HST and so on and these will be properly adjusted to UTC (Coordinated Universal Time) for transfer to other applications via microformat encoding. Gregorian calendar dates are required. Display in Julian or Chinese calendar date is possible using parameter 2.
|ISO8601=: (optional) if present, this ISO8601 date/time value is emitted instead of the value derived from parameter 1.
|BCE=: (required for BCE dates) set to yes if the date is BC.
|timezone= or |tz=: (required if timezone information specified) Set to yes if the time is UTC or if the location, timezone, or timezone offset is specified.

Ambiguous times and dates

For the years 99 BC to 99AD especially, microformats may not be emitted properly unless expressed in the form YYYY-MM-DD. For users uninterested in microformats, it should be noted that this restriction has no known impacts other than microformat data which are currently invisible to users. The user of course may express the display form in the second parameter however they would like. Example: 1-2-3 is interpreted as February 3, 1 A.D, and emitted in that form via microformats when the user may have intended something else. Other 3 digit years may be misinterpreted as well, so best practice is to use leading zeros to make a 4 digit year for this date range. For example, February 274 will be interpreted as February 27, 2004. Instead, use "February 0274". Background: There is a good rationale for the behavior of the system function which actually does the hard work of this template. It is very unusual for people to mention such dates so long ago, so when we really mean this date, we must specify a 4 digit date. Outside of this period with ambiguous years, users may use free text dates without this restriction. Bot runs may make a conversion of non 4 digit years to 4 digits (with leading zeros) in order to refine Wikipedia's quality of microformat dates. These changes will not affect display, but for those curious, this is the rationale for such bot manipulations.

Time zones

Most time zone abbreviations as well as a large number of place names are recognized. (See recognized timezone values table.)
