Announcement: On
November 13, 2024, all users will need to
use a Cloud project in order to access Earth Engine. After this date, continued individual access without a Cloud project will require
an exception.
ee.Date
Constructs a new Date object.
Usage | Returns | ee.Date(date, tz) | Date |
Argument | Type | Details | date | ComputedObject|Date|Number|String | The date to convert, one of: a number (number of milliseconds since the epoch), an ISO Date string, a JavaScript Date or a ComputedObject. |
tz | String, optional | An optional timezone only to be used with a string date. |
Examples
Code Editor (JavaScript)
// Numeric inputs are interpreted as milliseconds from Unix epoch.
print(ee.Date(0)); // Date (1970-01-01 00:00:00)
// Scale factors can make numerical inputs more readable (e.g. 60 seconds).
print(ee.Date(60 * 1000)); // Date (1970-01-01 00:01:00)
// ISO 8601 date string input examples.
print(ee.Date('2020')); // Date (2020-01-01 00:00:00)
print(ee.Date('2017-6-24')); // Date (2017-06-24 00:00:00)
print(ee.Date('2017-06-24')); // Date (2017-06-24 00:00:00)
print(ee.Date('2017-6-24T00:14:46')); // Date (2017-06-24 00:14:46)
print(ee.Date('2017-06-24T23:59:59')); // Date (2017-06-24 23:59:59)
// With an optional time zone.
print(ee.Date('2020', 'US/Mountain')); // Date (2020-01-01T07:00:00)
// Convert JavaScript now to Earth Engine Date
print(ee.Date(Date.now()));
Python setup
See the
Python Environment page for information on the Python API and using
geemap
for interactive development.
import ee
import geemap.core as geemap
Colab (Python)
