Unix Timestamp Converter

Epoch time.
Human time.

Current Unix timestamp…

Paste a Unix timestamp — seconds, milliseconds, microseconds or nanoseconds are detected automatically — or a date like 2026-01-01 12:00, and see it in UTC, ISO 8601, your local time zone and relative time.

Notable timestamps

Seconds, milliseconds or more?

A 10-digit number is seconds (most Unix tools, PHP, Python time.time()), 13 digits is milliseconds (JavaScript Date.now(), Java), 16 digits is microseconds and 19 digits nanoseconds (Go, some databases). The converter detects which from the length and tells you how it read your input.

Frequently asked questions

What is a Unix timestamp?
The number of seconds since 1 January 1970 00:00:00 UTC (the "Unix epoch"). JavaScript and many APIs use milliseconds instead, which have three more digits.
What is the year 2038 problem?
Systems that store timestamps as signed 32-bit integers overflow on 19 January 2038. Modern systems use 64-bit values, which last for billions of years.
