Understanding Epoch Time
Epoch time provides a single number that represents any moment in time. Instead of dealing with years, months, days, hours, and timezones, you just have one integer that increments every second.
This makes epoch time ideal for storing timestamps in databases, comparing times across different systems, and performing date calculations.
Epoch Time Reference
| Epoch Time | Human Date (UTC) | Note |
|---|---|---|
| 0 | Jan 1, 1970 00:00:00 | Unix Epoch start |
| 86400 | Jan 2, 1970 00:00:00 | One day later |
| 604800 | Jan 8, 1970 00:00:00 | One week later |
| 1000000000 | Sep 9, 2001 01:46:40 | 1 billion seconds |
| 1700000000 | Nov 14, 2023 22:13:20 | 1.7 billion seconds |
| 2147483647 | Jan 19, 2038 03:14:07 | 32-bit limit (Y2K38) |
Epoch Time Units
- 1 minute = 60
- 1 hour = 3,600
- 1 day = 86,400
- 1 week = 604,800
- 30 days = 2,592,000
- 365 days = 31,536,000
- 10 years ≈ 315,360,000
- Add 1 hour: +3600
- Add 1 day: +86400
- Add 1 week: +604800

What is epoch time?
Epoch time (Unix time, POSIX time) is the number of seconds since January 1, 1970, 00:00:00 UTC. It's a universal way to represent time in computing.
What is the current epoch time?
The current epoch time is displayed at the top of this page. It updates every second and represents the exact number of seconds since the Unix epoch.
How do I convert epoch time to a readable date?
Use our epoch converter tool. Paste your epoch timestamp and instantly see the human-readable date. Works with both seconds (10 digits) and milliseconds (13 digits).
Why is epoch time useful?
Epoch time is timezone-independent, compact (single integer), easy to compare, and simple to use in calculations. It's the standard for timestamps in most programming languages.
