JavaScript / TypeScript (Node.js & Browser)
const timestamp = 1617235200000;
const date = new Date(timestamp);
console.log(date.toISOString()); // 2021-04-01T00:00:00.000ZPython (datetime)
import datetime
timestamp = 1617235200000
dt = datetime.datetime.fromtimestamp(timestamp / 1000.0, tz=datetime.timezone.utc)
print(dt.isoformat()) # 2021-04-01T00:00:00.000ZFrequently Asked Questions
What historical or future date does the timestamp 1617235200000 represent?
The Unix epoch timestamp 1617235200000 precisely represents Thu, 01 Apr 2021 00:00:00 GMT, which follows the ISO 8601 standard format of 2021-04-01T00:00:00.000Z.
Is 1617235200000 measured in seconds or milliseconds?
It is measured in milliseconds. We can determine this programmatically because it contains exactly 13 digits. In software engineering, standard 10-digit Unix timestamps represent seconds, whereas 13-digit timestamps represent milliseconds since the epoch.
How do I parse 1617235200000 programmatically in JavaScript or Python?
In JavaScript, you can parse it using: new Date(1617235200000). In Python, you would use: datetime.datetime.fromtimestamp(1617235200000 / 1000).
