[[mapping-date-format]]

|
=== `format`
|
|
|
|
In JSON documents, dates are represented as strings. Elasticsearch uses a set
|
|
of preconfigured formats to recognize and parse these strings into a long
|
|
value representing _milliseconds-since-the-epoch_ in UTC.
|
|
|
|
Besides the <<built-in-date-formats,built-in formats>>, your own
|
|
<<custom-date-formats,custom formats>> can be specified using the familiar
|
|
`yyyy/MM/dd` syntax:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
PUT my_index?include_type_name=true
|
|
{
|
|
"mappings": {
|
|
"_doc": {
|
|
"properties": {
|
|
"date": {
|
|
"type": "date",
|
|
"format": "yyyy-MM-dd"
|
|
}
|
|
}
|
|
}
|
|
}
|
|
}
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
|
|
Many APIs which support date values also support <<date-math,date math>>
|
|
expressions, such as `now-1m/d` -- the current time, minus one month, rounded
|
|
down to the nearest day.
|
|
|
|
[[custom-date-formats]]
|
|
==== Custom date formats
|
|
|
|
Completely customizable date formats are supported. The syntax for these is explained
|
|
http://www.joda.org/joda-time/apidocs/org/joda/time/format/DateTimeFormat.html[in the Joda docs].
|
|
|
|
[[built-in-date-formats]]
|
|
==== Built In Formats
|
|
|
|
Most of the below formats have a `strict` companion format, which means that
|
|
year, month and day parts of the week must use respectively 4, 2 and 2 digits
|
|
exactly, potentially prepending zeros. For instance a date like `5/11/1` would
|
|
be considered invalid and would need to be rewritten to `2005/11/01` to be
|
|
accepted by the date parser.
|
|
|
|
To use them, you need to prepend `strict_` to the name of the date format, for
|
|
instance `strict_date_optional_time` instead of `date_optional_time`.
|
|
|
|
These strict date formats are especially useful when
|
|
<<date-detection,date fields are dynamically mapped>> in order to make sure to
|
|
not accidentally map irrelevant strings as dates.
|
|
|
|
The following tables lists all the defaults ISO formats supported:
|
|
|
|
`epoch_millis`::
|
|
|
|
A formatter for the number of milliseconds since the epoch. Note, that
|
|
this timestamp is subject to the limits of a Java `Long.MIN_VALUE` and
|
|
`Long.MAX_VALUE`.
|
|
|
|
`epoch_second`::
|
|
|
|
A formatter for the number of seconds since the epoch. Note, that this
|
|
timestamp is subject to the limits of a Java `Long.MIN_VALUE` and `Long.
|
|
MAX_VALUE` divided by 1000 (the number of milliseconds in a second).
|
|
|
|
[[strict-date-time]]`date_optional_time` or `strict_date_optional_time`::
|
|
|
|
A generic ISO datetime parser where the date is mandatory and the time is
|
|
optional.
