Unix Timestamp Converter

Convert Unix timestamps to human-readable dates and generate Unix timestamps from date and time.

How it works

Timestamp -> Date

UTC date output
Local date output
ISO 8601 date output

Date -> Timestamp

Seconds
Milliseconds

How to convert a Unix timestamp

  1. Enter a 10-digit timestamp in seconds or a 13-digit timestamp in milliseconds.
  2. Read the UTC, local date-time, and ISO 8601 results.
  3. To create a timestamp, choose a date, time, and time zone in the second section.
  4. Copy the seconds or milliseconds result for your API, database, log, or code.

Common timestamp uses

Convert API values, inspect log entries, prepare database records, schedule events, and compare dates across time zones.

Timestamp tips

  • Check whether your source uses seconds or milliseconds before converting.
  • Use UTC when you need a consistent value across locations.
  • Choose the intended time zone before generating a timestamp from a date.

Unix Timestamp Converter FAQ

What is a Unix timestamp?

A Unix timestamp represents a moment as elapsed time since 1 January 1970 UTC. It is commonly stored in seconds or milliseconds.

Does this converter accept seconds and milliseconds?

Yes. Enter a 10-digit Unix timestamp in seconds or a 13-digit Unix timestamp in milliseconds.

What is the difference between UTC and local time?

UTC is a global reference time. Local time applies the selected time zone and its applicable daylight-saving rules.

Is ISO 8601 supported?

Yes. The timestamp-to-date result includes an ISO 8601 representation that is convenient for APIs, logs, and interchange.

Is my date or timestamp stored?

No. Conversions happen locally in your browser and DevKit does not upload or store the values you enter.
