About Timestamp Converter Online
This tool converts between Unix timestamps (seconds or milliseconds since the Unix epoch — January 1, 1970, 00:00:00 UTC) and human-readable date and time strings.
Unix timestamps are the standard way servers, databases, APIs, and programming languages represent points in time internally. Converting them is a daily task for developers inspecting log files, debugging database records, or reading API responses that return epoch values.
The tool handles both second-precision timestamps (10 digits) and millisecond-precision timestamps (13 digits). It also shows the current timestamp so you can use it as a reference point.
How to use this tool
How to convert between Unix timestamps and ISO dates
Paste a timestamp or date
Type into the Value field: a 10-digit Unix seconds value, a 13-digit Unix milliseconds value, or any ISO date string (e.g. 2026-05-20T14:00:00Z). Leading/trailing whitespace is trimmed.
Pick a display timezone
Localized display (IANA zone) accepts UTC, Europe/London, Europe/Paris, America/New_York, America/Los_Angeles, Asia/Dubai, Asia/Tokyo, or Australia/Sydney. Only the localized rendering changes — the underlying instant does not.
Press Run
The tool detects whether your input is interpretedAs unix_seconds / unix_milliseconds / date_string and reports it back so you can confirm parsing.
Read all output forms
Result returns iso (UTC), unixSeconds, unixMs, displayTimeZone, and localizedInZone (full date + long time in your chosen zone). Copy whichever form your downstream system expects.
