Usage
Display a sequence of backward counting to indicate the time remaining before an event is scheduled to occur.
The amp-date-countdown
provides countdown time data that you can render in your AMP page. By providing specific attributes in the amp-date-countdown
tag, the amp-date-countdown
extension returns a list of time parameters, which you can pass to an amp-mustache
template for rendering. Refer to the list below for each returned time parameter.
<amp-date-countdown timestamp-seconds="2147483648" layout="fixed-height" height="50" > <template type="amp-mustache"> <p class="p1"> {{d}} days, {{h}} hours, {{m}} minutes and {{s}} seconds until <a href="https://en.wikipedia.org/wiki/Year_2038_problem">Y2K38</a>. </p> </template> </amp-date-countdown>
Returned time parameters
This table lists the format you can specify in your Mustache template:
Format | Meaning |

Migrating from 0.1
The experimental 1.0
version of amp-date-countdown
uses the attribute name count-up
instead of data-count-up
as in 0.1
to support the "count up" feature. See the count-up
section under Attributes
below for more details.
Standalone use outside valid AMP documents
Bento allows you to use AMP components in non-AMP pages without needing to commit to fully valid AMP. You can take these components and place them in implementations with frameworks and CMSs that don't support AMP. Read more in our guide Use AMP components in non-AMP pages.

Attributes
You must specify at least one of these required attributes: end-date
,
timeleft-ms
, timestamp-ms
, timestamp-seconds
.
end-date
An ISO formatted date to count down to. For example, 2020-06-01T00:00:00+08:00
timestamp-ms
A POSIX epoch value in milliseconds; assumed to be UTC timezone. For example,
timestamp-ms="1521880470000"
.
timestamp-seconds
A POSIX epoch value in seconds; assumed to be UTC timezone. For example,
timestamp-seconds="1521880470"
.
timeleft-ms
A value in milliseconds left to be counting down. For example, 48 hours left
timeleft-ms="172800000"
.
offset-seconds (optional)
A positive or negative number that represents the number of seconds to add or
subtract from the end-date
. For example, offset-seconds="60"
adds 60 seconds
to the end-date.
when-ended (optional)
Specifies whether to stop the timer when it reaches 0 seconds. The value can be
set to stop
(default) to indicate the timer to stop at 0 seconds and will not
pass the final date or continue
to indicate the timer should continue after
reaching 0 seconds.
locale (optional)
An internationalization language string for each timer unit. The default value
is en
(for English).
Supported values:
Code | Language |
---|---|
de | German |
en | English |
es | Spanish |
fr | French |
id | Indonesian |
it | Italian |
ja | Japanese |
ko | Korean |
nl | Dutch |
pt | Portuguese |
ru | Russian |
th | Thai |
tr | Turkish |
vi | Vietnamese |
zh-cn | Chinese Simplified |
zh-tw | Chinese Traditional |
biggest-unit (optional)
Allows the amp-date-countdown
component to calculate the time difference based
on the specified biggest-unit
value. For example, assume there are 50 days 10 hours
left, if the biggest-unit
is set to hours
, the result displays
1210 hours
left.
- Supported values:
days
,hours
,minutes
,seconds
- Default:
days
count-up (optional)
Include this attribute to reverse the direction of the countdown to count up instead. This is useful to display the time elapsed since a target date in the past. To continue the countdown when the target date is in the past, be sure to include the when-ended
attribute with the continue
value. If the target date is in the future, amp-date-countdown
will display a decrementing (toward 0) negative value.
0.1
which uses the data-count-up
attribute to toggle this feature. The behavior of the feature is otherwise identical to 0.1
. Events
The amp-date-countdown
component exposes the following event that you can use
AMP on-syntax to trigger:
Timeout
When the timer times out. For this action to function, when-ended
must be
set to stop
. You can only run low-trust actions such as amp-animation
and
amp-video
actions when the timer times out. This is to enforce AMP's UX
principle of not allowing page content to reflow without explicit user actions.

Example: Demonstrating usage of timeout event
<h1 id="sample"> When Timer hits 0, will hide the timer itself and hide this message. </h1> <amp-animation id="hide-timeout-event" layout="nodisplay"> <script type="application/json"> { "duration": "1s", "fill": "both", "selector": "#ampdate, #sample", "keyframes": {"visibility": "hidden"} } </script> </amp-animation> <amp-date-countdown id="ampdate" end-date="2018-07-17T06:19:40+08:00" on="timeout: hide-timeout-event.start" height="400" width="400" when-ended="stop" locale="en" > <template type="amp-mustache"> <h1>Countdown Clock</h1> <div> {{dd}} : {{hh)) : {{mm}} : {{ss}} </div> </template> </amp-date-countdown>
