about the tool

What Is an Epoch Converter?

An epoch time converter (also called an epoch converter or epoch unix time converter) is a utility that translates between Unix time and human-readable dates and times. Unix time, also known as the Unix timestamp, POSIX time, or epoch time, counts the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC, the moment known as the Unix epoch. Because a timestamp is a single number that identifies an exact instant anywhere on the planet, it is the standard way that computers, databases, and logs record moments in time.

A Unix Epoch Converter That Works Both Ways

This page is a full Unix epoch converter: it converts timestamps to dates and dates back to timestamps. Paste any timestamp into the converter and you instantly see the equivalent date and time in your local timezone, in UTC, and in ISO 8601 format. Switch to date-to-epoch mode, type any date string, or pick a moment with the built-in date picker, and the tool returns the matching Unix timestamp in seconds, milliseconds, or microseconds. In other words, it is an epoch timestamp converter that combines a timestamp-to-epoch and a date epoch converter in one tool. However you need to convert epoch time, the direction is covered.

UTC Epoch Converter and Local Epoch Converter in One

A Unix timestamp is absolute. It marks the same instant everywhere on Earth. How that instant reads, however, changes with your timezone. This tool works as both a UTC epoch converter and a local epoch converter: choose UTC for server logs and API payloads, or pick your local timezone (or any of the hundreds of IANA timezones) and every result renders in the context you need. The live clock at the top of the page ticks in both local and UTC time, and your timezone preference is remembered between visits.

Seconds, Milliseconds, and Microseconds: Auto-Detected

Not every epoch time counts seconds. Many web APIs return epoch time in milliseconds, and high-precision systems work in microseconds. This epoch time converter detects the unit automatically: paste 1722750000, 1722750000123, or 1722750000123456 and it knows the difference. You can also lock the unit manually for ambiguous values. No more guessing whether that number is seconds or milliseconds.

A Linux Epoch Converter for Developers

Developers who live in the terminal spend a lot of time reading Unix timestamps in file listings, logs, and database rows. This tool doubles as a Linux epoch converter for that work: paste a timestamp from stat, dmesg, or a MySQL and Postgres dump and read the date instantly. It also generates copy-ready code snippets in ten languages: JavaScript, Python, PHP, SQL, Go, Java, C#, Rust, C++, and PowerShell, so you can produce the current epoch time in your own stack. Whether you need to convert time to epoch for a query or decode a timestamp from a log, the answer is one paste away.

Batch Convert Many Timestamps at Once

Need to convert a whole list? The batch converter accepts one timestamp per line (or values separated by commas and spaces) and converts every row in a single pass. Each result is copied with one click, and the full table exports as a spreadsheet-ready TSV or CSV. It is the fastest online epoch converter for bulk timestamp-to-date work.

Specialized Converters for Every Timestamp Format

Unix time is just one of many epoch systems, and each of the others gets its own dedicated converter on this site: a snowflake ID converter for Discord and Twitter/X 64-bit IDs, an LDAP timestamp converter for Active Directory 100-nanosecond values, a GPS time converter for week and seconds-of-week readings, an NTP timestamp converter for seconds since 1900, a .NET ticks converter for DateTime ticks since year 1, a Mac HFS+ timestamp converter for seconds since 1904, and an Excel date converter for OADate serial numbers. A second wave of specialists fills the remaining gaps: a UUID v1 / v7 & ULID converter that extracts the creation time from time-ordered IDs, a Chrome / WebKit timestamp converter for microseconds since 1601, a Cocoa Core Data timestamp converter for seconds since 2001, a timezone converter for moving a wall-clock time between two zones, a Unix hex timestamp converter for hexadecimal epoch values, a Year 2038 countdown to the 32-bit overflow, and a common Unix timestamps reference. Each landing page explains the epoch, the arithmetic, worked examples, and the code you need, and the programming guides cover getting and converting Unix time in ten languages: JavaScript, Python, PHP, Go, Java, C#, Rust, C++, SQL, and PowerShell.

faq

Epoch Converter FAQ

Quick answers about Unix time, timestamps, timezones, and this tool, including the questions developers ask most.

How do I convert IST to epoch?

To convert IST (Indian Standard Time, UTC+5:30) to epoch, select Asia/Kolkata from the timezone list and type your IST date and time into the date-to-timestamp mode. The tool converts it to a Unix timestamp you can use in code. The reverse also works: paste a timestamp and read it back in IST.

What is the Unix epoch?

The Unix epoch is the reference point for Unix time: January 1, 1970, 00:00:00 UTC. Every Unix timestamp is the number of seconds (or milliseconds) elapsed since that instant. It is the standard way computers, operating systems, databases, and logs record an exact moment in time, independent of timezone.

What is a timestamp converter?

A timestamp converter translates Unix time into a human-readable date and time, and back again. Paste a value like 1722750000 and you get the equivalent date in your local timezone and UTC; type a date and the tool returns its timestamp in seconds, milliseconds, or microseconds. It is the fastest way to decode the numbers you see in logs and APIs.

How do I convert epoch to time?

To convert epoch to time, paste the timestamp into the converter and read the result as a human-readable date and time. Since a Unix timestamp is the number of seconds since January 1, 1970, UTC, the converter works it backwards: it shows the exact moment that number represents, in UTC and in your local timezone. For example, 1722750000 converts to August 4, 2024. If you need the other direction (a date back to a timestamp), switch to date-to-epoch mode.

What is an epoch converter used for?

An epoch converter tool (the kind you might search for as "converter epoch" or "epoch time converter") is used to translate Unix timestamps into dates and dates into timestamps. Developers use it to decode the numbers in server logs, file timestamps, and API payloads, and to generate the epoch values their code needs. This tool does all of that in both directions, auto-detects seconds, milliseconds, and microseconds, and supports every timezone.

How do I convert epoch to UTC?

To convert epoch to UTC, paste the timestamp into the converter and choose UTC from the timezone list. Every result then renders in Coordinated Universal Time, which is what most server logs, databases, and API payloads use. The live clock at the top of the page also ticks in both UTC and your local time.

How do I convert epoch to EST?

To convert epoch to EST (Eastern Standard Time, UTC−5), paste the timestamp into the converter and choose America/New_York from the timezone list. The tool renders the exact local time, including the daylight-saving offset (EDT, UTC−4, during summer months), so the same timestamp reads differently in January and July.

How do I convert epoch to PST?

To convert epoch to PST (Pacific Standard Time, UTC−8), paste the timestamp into the converter and choose America/Los_Angeles from the timezone list. You get the precise local time with the correct daylight-saving offset (PDT, UTC−7, during summer months) automatically applied.

What is POSIX time?

POSIX time is another name for Unix time: the number of seconds since January 1, 1970, 00:00:00 UTC, as defined by the POSIX standard (also called the Unix epoch, epoch time, or Unix timestamp). A POSIX time converter translates those seconds into a human-readable date and back, exactly what this tool does, in seconds, milliseconds, or microseconds.

What format is epoch time?

Epoch time is stored as a single integer counting seconds since January 1, 1970, 00:00:00 UTC (for example 1722750000). The epoch format appears as a 10-digit number for seconds, 13 digits for milliseconds, and 16 digits for microseconds. This tool auto-detects the unit, so you never have to count digits yourself.

What is the best converter for epoch timestamps?

The best converter for epoch timestamps handles both directions, auto-detects seconds, milliseconds, and microseconds, and supports every timezone, including UTC and IST. This tool converts one value or a whole batch in a single paste, generates copy-ready code snippets, and runs entirely in your browser with no sign-up or paywall.

What is the best epoch converter tool?

The best epoch converter tool is free, instant, private, and reliable. This online epoch converter detects timestamp precision automatically, converts to and from dates in any timezone, exports batch results as TSV or CSV, and never uploads your data because everything runs locally in your browser. It is trusted by developers for debugging logs and queries.

What is an epoch converter?

An epoch converter is a utility that converts between Unix timestamps and human-readable dates and times. Since Unix time counts seconds since January 1, 1970, UTC, a converter is essential for reading the numbers that appear in logs, file systems, databases, and APIs, turning them into dates anyone can understand, and turning dates back into timestamps for code.

How do I convert a Discord snowflake ID to a date?

A Discord snowflake ID is a 64-bit integer: the top 41 bits are a timestamp in milliseconds since the Discord epoch (January 1, 2015), and the remaining bits store the worker, process, and sequence. To decode one, shift the ID right by 22 and add 1420070400000 to get epoch milliseconds, then format it as a date. Paste the ID into the snowflake ID converter for the full breakdown: timestamp, worker, process, and sequence.

What is an LDAP or Active Directory timestamp?

Active Directory and LDAP record moments like password changes and account expirations as 100-nanosecond intervals since January 1, 1601 UTC. A typical value is 18 digits long, for example 134305344000000000. To convert one to Unix time, divide by 10,000,000 and subtract 11644473600 seconds. The LDAP timestamp converter does exactly that, in both directions.

What are GPS week and seconds-of-week?

GPS receivers count time as a week number plus seconds since the GPS epoch: midnight UTC on January 6, 1980. GPS time ignores leap seconds, so its clock currently runs 18 seconds ahead of UTC. To convert, use Unix time = GPS total seconds + 315964800 − 18. The GPS time converter handles weeks, seconds-of-week, and the leap-second offset.
