How to Convert Unix Epoch Timestamps
The Epoch & Unix Timestamp Converter translates raw Unix timestamps (seconds, milliseconds, microseconds, or nanoseconds since January 1, 1970 00:00:00 UTC) into human-readable calendar dates and ISO 8601 strings, and converts human dates into numeric timestamps. It also features a real-time ticking clock and copyable code snippets for developers.
Step-by-Step Instructions:
- Timestamp to Date: Paste or type any 10-digit (seconds) or 13-digit (milliseconds) Unix timestamp into the input box, or click Use Current Time.
- Automatic Unit Detection: The tool automatically detects whether the input is in seconds, milliseconds, microseconds, or nanoseconds.
- Instant Date Breakdown: View the decoded GMT / UTC Date, Your Device Local Time, ISO 8601 String, Relative Time (e.g. 2 hours ago), and Day of the Year.
- Date to Timestamp: Switch to the Date to Timestamp tab, choose your Year, Month, Day, and Time, and generate exact Unix epoch seconds and milliseconds.
- One-Click Copy: Click the copy icon next to any value to copy it instantly.
What is Unix Epoch Time?
⏱️ The 1970 Epoch Benchmark
Unix time measures the number of non-leap seconds that have elapsed since the Unix epoch: January 1, 1970 00:00:00 UTC.
🌐 Universal Time Standard
Because Unix timestamps are timezone-agnostic, they are the universal standard for logging events, database record tracking, and cross-server synchronization.
Getting Current Epoch in Code
| Language / Database | Code Snippet (Current Epoch Seconds) |
|---|---|
| JavaScript / Node | Math.floor(Date.now() / 1000) |
| Python | import time; int(time.time()) |
| PHP | time() |
| MySQL | UNIX_TIMESTAMP() |
| Go | time.Now().Unix() |
| C# / .NET | DateTimeOffset.UtcNow.ToUnixTimeSeconds() |
Frequently Asked Questions
What is the Year 2038 Problem (Y2K38)?
On January 19, 2038 at 03:14:07 UTC, 32-bit signed integers will overflow from 2,147,483,647 to -2,147,483,648, wrapping the year back to 1901. Modern 64-bit systems have solved this, safe for billions of years.
How do I convert milliseconds to seconds in Unix time?
Simply divide the 13-digit millisecond value by 1,000 (e.g. 1787612000000 / 1000 = 1787612000).
