Unix Timestamp to Date

Paste a Unix timestamp to see the exact date and time in IST, UTC, your local zone and ISO 8601.

What is the Unix Timestamp to Date?

Converting epoch timestamps to dates is common when reading logs, databases and API responses.

How does it work?

The unit is detected from the digit count and the value is formatted in several time zones, with a relative description like “3 days ago”.

Formula

Date = new Date(timestamp × 1000)

Example

1767225600 is 1 January 2026, 00:00:00 UTC — 5:30 AM IST.
