Event Date: The date-time or interval during which an Event occurred. For occurrences, this is the date-time when the event was recorded. Not suitable for a time in a geological context. Recommended best practice is to use an encoding scheme, such as ISO 8601:2004(E).

Notes: The eventDate term can be used to capture specific dates at various levels of resolution as well as periods of time with distinct beginnings and endings. It is for this reason that the legacy beginning and ending dates were not retained from previous versions of Darwin Core. Note that eventDate cannot be used to capture information about events on geological time scales. To do so, use the terms in the GeologicalContext class.

Further explanation of the International Standards Organization standard ISO 8601 can be found at http://en.wikipedia.org/wiki/ISO_8601, but here are some examples:

year only: 2010

year and month: 2010-01

year, month, and day: 2010-01-17

year, month, day, and UTC time: 2010-01-17T09:26Z

year, month, day, and local time: 2010-01-17T09:33:59-0300

interval between years: 2009/2010

interval between months: 2009-02/2010-01

interval between months: 2009-02/10

interval between days: 2009-02-12/2009-10-08

interval between times on one day: 2010-01-17T12:26Z/12:52:17Z

interval between times on different days: 1963-03-08T14:07-0600/1971-08-03T06:00-0000

It is not possible to render a month without a year, or a day without a month and year, or other vague or partial dates and times such as "spring 2010." Dates such as these should be captured in the verbatimEventDate.

Example(s): "1963-03-08T14:07-0600" is 8 Mar 1963 2:07pm in the time zone six hours earlier than UTC, "2009-02-20T08:40Z" is 20 Feb 2009 8:40am UTC, "1809-02-12" is 12 Feb 1809, "1906-06" is Jun 1906, "1971" is just that year, "2007-03-01T13:00:00Z/2008-05-11T15:30:00Z" is the interval between 1 Mar 2007 1pm UTC and 11 May 2008 3:30pm UTC, "2007-11-13/15" is the interval between 13 Nov 2007 and 15 Nov 2007.

Español (Spanish)
Fecha del Evento: La fecha y hora o el intervalo durante el cual se produjo un evento. Para los registros de especies, esta es la fecha y hora cuando el evento se registró. No es adecuado para un momento en un contexto geológico. La práctica recomendada es utilizar un esquema de codificación, tal como ISO 8601:2004 (E).
Ejemplo: "1963-03-08T14:07-0600" es 8 de marzo de 1963 2:07pm en zona horaria seis horas más temprano que UTC, "2009-02-20T08:40Z" es 20 de febrero 2009 8:40am UTC, "1809-02-12" es 12 de febrero de 1809, "1906-06" es junio de 1906, "1971", "2007-03-01T13:00:00Z/2008-05-11T15:30:00Z" es el intervalo entre el 1 de marzo de 2007 1pm UTC y 11 de mayo de 2008 3:30pm UTC, "2007-11-13/15" es el intervalo entre el 13 de noviembre de 2007 y 15 de noviembre de 2007.

Date de l'événement: La date-heure ou l'intervalle pendant lequel le sujet a été récolté/observé. Ne convient pas pour un temps dans un contexte géologique. Il est recommandé d'utiliser un schéma de codage, tels que l'ISO 8601:2004 (E).
Exemple: "1963-03-08T14:07-0600" correspond au 8 mars 1963 14:07 dans le fuseau horaire remontant six heures avant l'UTC, "2009-02-20T08:40Z" correspond au 20 février 2009 8:40 UTC, "1809-02-12" correspond au 12 février 1809, "1906-06" correspond à juin 1906, "1971" correspond à cette année uniquement, "2007-03-01T13:00:00Z/2008-05-11T15:30:00Z" correspond à l'intervalle entre le 1er mars 2007 à 13h UTC et le 11 mai 2008 à 15h30 UTC, "2007-11-13/15" correspond à l'intervalle entre le 13 novembre 2007 et le 15 novembre 2007.
