Unix Timestamp Converter

Convert Unix epoch timestamps to human-readable dates and dates back to timestamps, in UTC or any time zone. Free, private, and 100% in your browser.

Current Unix time

Timestamp or Date

Dates without an offset (like 2024-05-11 10:30) are read in the selected time zone.

Convert Epoch Time to a Date

Logs, databases, APIs, and JWTs store time as Unix timestamps because they are compact and unambiguous. Reading them is another story. Paste a timestamp to see exactly which date and time it represents, in your time zone and in UTC.

Get the current Unix timestamp
JavaScript   Math.floor(Date.now() / 1000)
Python       int(time.time())
Go           time.Now().Unix()
Java         Instant.now().getEpochSecond()
PHP          time()
Bash         date +%s
PostgreSQL   SELECT EXTRACT(EPOCH FROM now());
MySQL        SELECT UNIX_TIMESTAMP();

Features

  • Detects the unit

    10 digits are seconds, 13 milliseconds, 16 microseconds, and 19 nanoseconds. You can also pick the unit yourself.

  • Both directions

    Paste a timestamp to get the date, or paste a date (ISO 8601, RFC 2822, or 2024-05-11 10:30) to get the timestamp.

  • Any time zone

    Show results in your local zone, UTC, or any IANA zone such as America/New_York, with the correct daylight saving offset.

  • Every format

    ISO 8601 with offset, RFC 2822 / HTTP date, seconds, milliseconds, microseconds, nanoseconds, ISO week, day of year, and Excel serial date.

  • Batch conversion

    Convert up to 500 timestamps from logs at once and copy the results as tab-separated text.

  • Nanosecond precision

    Large values are handled with BigInt, so 19-digit nanosecond timestamps keep every digit.

How to Convert a Unix Timestamp

  1. Paste a timestamp or a date into the input, or pick a date.
  2. Check the detected unit, or choose seconds, milliseconds, microseconds, or nanoseconds.
  3. Select the time zone to display the result in.
  4. Copy the format you need: ISO 8601, RFC 2822, or epoch values.

Frequently Asked Questions

What is a Unix timestamp?

A Unix timestamp (epoch time, POSIX time) is the number of seconds since January 1, 1970 at 00:00:00 UTC, not counting leap seconds. It is the same everywhere in the world, which makes it ideal for storing and comparing times.

Is my timestamp in seconds or milliseconds?

Count the digits. Current timestamps in seconds have 10 digits (for example 1715423000), in milliseconds 13 digits (1715423000000), in microseconds 16, and in nanoseconds 19. JavaScript's Date.now() and Java's System.currentTimeMillis() return milliseconds; most Unix tools and Python's time.time() use seconds.

What time zone is a Unix timestamp in?

None: a timestamp always refers to a moment in UTC. Only its display depends on a time zone. That is why the same timestamp shows different clock times in different zones.

What is the year 2038 problem?

Systems that store Unix time as a signed 32-bit integer overflow at 2147483647, which is January 19, 2038 at 03:14:07 UTC. After that, the value wraps to a negative number (1901). Use 64-bit integers to avoid it.

How are dates without a time zone interpreted?

A date such as 2024-05-11 10:30:00 is read as a wall-clock time in the time zone you select. Dates with Z or an offset like +02:00 are exact instants and ignore the selection.
