Developer Implementation
JavaScript / TypeScript (Node.js & Browser)
const timestamp = 1638316800;
const date = new Date(timestamp * 1000);
console.log(date.toISOString()); // 2021-12-01T00:00:00.000ZPython (datetime)
import datetime
timestamp = 1638316800
dt = datetime.datetime.fromtimestamp(timestamp, tz=datetime.timezone.utc)
print(dt.isoformat()) # 2021-12-01T00:00:00.000ZFrequently Asked Questions
What historical or future date does the timestamp 1638316800 represent?
The Unix epoch timestamp 1638316800 precisely represents Wed, 01 Dec 2021 00:00:00 GMT, which follows the ISO 8601 standard format of 2021-12-01T00:00:00.000Z.
Is 1638316800 measured in seconds or milliseconds?
It is measured in seconds. We can determine this programmatically because it contains exactly 10 digits. In software engineering, standard 10-digit Unix timestamps represent seconds, whereas 13-digit timestamps represent milliseconds since the epoch.
How do I parse 1638316800 programmatically in JavaScript or Python?
In JavaScript, you can parse it using: new Date(1638316800 * 1000). In Python, you would use: datetime.datetime.fromtimestamp(1638316800).
