Unix Timestamp Converter (Epoch Time)

What is a Unix timestamp?

A Unix timestamp (also called epoch time) is the number of seconds that have elapsed since 00:00:00 UTC on Thursday, 1 January 1970 — a moment called the Unix epoch. For example, the timestamp 1760620000 means exactly 1,760,620,000 seconds after the epoch. Because it counts from one fixed reference point, a timestamp describes the same instant everywhere on Earth: it is completely timezone-independent, which is why databases, APIs, and log files love it.

The catch is readability — no human looks at 1760620000 and sees “October 2026”. That is what this converter is for: paste any timestamp and it instantly becomes a date you can read, in every common format. It works entirely in your browser, with no signup and no data ever leaving your device.

Seconds, milliseconds, microseconds, nanoseconds — which is it?

The single most confusing thing about epoch time is the unit. Different platforms picked different precisions, and a timestamp in the wrong unit looks like nonsense (milliseconds read as seconds point to the year 57700). The reliable rule is digit counting:

This converter applies that rule automatically — paste a timestamp of any length and it tells you which unit it detected. If it ever guesses wrong (a very old 10-digit seconds value and a truncated 10-digit millisecond value can look alike), the unit dropdown lets you override it by hand.

How to get the current timestamp in your language

Every mainstream language has a one-liner. Copy the one you need:

import time
time.time()          # e.g. 1760620000.123
int(time.time())     # integer seconds

Date.now()                     // e.g. 1760620000123
Math.floor(Date.now() / 1000)  // seconds

System.currentTimeMillis()        // e.g. 1760620000123
System.currentTimeMillis() / 1000  // seconds

time.Now().Unix()      // seconds
time.Now().UnixMilli() // milliseconds
time.Now().UnixNano()  // nanoseconds

time();  // e.g. 1760620000

What about negative timestamps and the Year 2038 problem?

Timestamps before 1 January 1970 are simply negative — -2208988800 is 1 January 1900, for example. This converter handles them correctly, so historical dates are no problem.

The famous Year 2038 problem is the mirror image: a signed 32-bit integer tops out at 2,147,483,647 seconds, which lands on Tuesday, 19 January 2038 at 03:14:07 UTC. One second later it overflows back to 1901. In 2026 this mostly threatens 32-bit embedded systems, old file formats, and legacy databases — modern 64-bit platforms store epoch time with room to spare for hundreds of billions of years, so your laptop and phone are safe.

Why this converter beats a search-engine snippet

Typing a timestamp into a search box gives you one date in one timezone, once. This converter gives you UTC, your local time, ISO 8601, and RFC 2822 at a glance, converts whole batches in one paste, works offline-friendly in a single page, and never sends your data anywhere. For developers debugging JWT expiry claims or log timestamps, the auto-detect alone saves a surprising amount of squinting.
