Epoch & Unix timestamp converter
Convert any epoch (Unix) timestamp into a readable date in IST, UTC or any timezone, and convert dates back to epoch seconds or milliseconds — with the unit (seconds vs milliseconds) auto-detected from the number of digits, and a live "current epoch" clock ticking at the top so you always have a reference value to copy.

How to use this tool
-
Paste a timestamp
Seconds or milliseconds are detected automatically from the digit count, and the assumption is shown on screen.
-
Pick a timezone
IST (Asia/Kolkata) and UTC are pinned to the top of the list; search any other zone.
-
Or convert the other way
Choose a date and time, and get its epoch value in seconds and milliseconds.
Questions people ask
What is Unix/epoch time?
The number of seconds elapsed since 00:00:00 UTC on 1 January 1970 — the reference point nearly every programming language, database and log file uses to represent a moment in time as a single integer instead of a formatted date string.
Is my timestamp in seconds or milliseconds?
10 digits is almost certainly seconds; 13 digits is almost certainly milliseconds; 16 digits is microseconds. This converter detects it automatically from the digit count and always states which it assumed, rather than silently guessing.
How do I convert a Unix timestamp to IST?
Paste the timestamp and pick Asia/Kolkata from the timezone list — it is pinned to the very top alongside UTC, since those are the two zones nearly every visitor here actually needs.
What is the current Unix timestamp right now?
The live clock at the top of this page shows it in both seconds and milliseconds, ticking once a second, with a tap-to-copy button on each.
What is the "year 2038 problem"?
Systems that store epoch time as a signed 32-bit integer will overflow on 19 January 2038, wrapping the timestamp back to a date in 1901 — modern 64-bit systems (which is nearly everything today) are unaffected.
