Epoch & Unix Timestamp Converter - Convert Between Timestamps and Dates
Our Epoch & Unix Timestamp Converter is a comprehensive tool designed for developers and professionals to easily convert between Unix timestamps and human-readable dates. With live current time display, multiple timezone support, and automatic unit detection, this tool provides everything you need for timestamp conversions.
How to Use the Epoch Converter
View Current Time
See the live current Unix timestamp in both seconds and milliseconds, updating every second.
Convert Timestamp to Date
Enter a Unix timestamp and see it converted to multiple date formats with timezone support.
Convert Date to Timestamp
Select a date and time to get the corresponding Unix timestamp in seconds and milliseconds.
Copy Results
Use the copy buttons to easily copy timestamps, dates, and formatted strings for your projects.
What is a Unix Timestamp?
A Unix timestamp (also called Epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC (the Unix Epoch). This standardized time format is widely used in computing systems, databases, and programming languages.
Key Points:
- • Seconds vs Milliseconds: Unix timestamps can be in seconds (10 digits) or milliseconds (13 digits)
- • Universal Format: Same timestamp represents the same moment worldwide
- • Programming Standard: Used in JavaScript, Python, PHP, and many other languages
- • Database Friendly: Easy to store, sort, and query in databases

Common Use Cases - When You Need Timestamp Conversion
API Development
Convert timestamps from API responses to readable dates for debugging and testing.
Database Queries
Convert between timestamp formats when working with database date fields.
Log Analysis
Decode Unix timestamps in log files to understand when events occurred.
JavaScript Development
Convert between Date.now() milliseconds and traditional Unix seconds.
Scheduling Systems

Data Migration
Convert timestamps between different systems and timezone formats.
Frequently Asked Questions
What is the difference between seconds and milliseconds?
Seconds timestamps are 10 digits (e.g., 1677628800), while milliseconds are 13 digits (e.g., 1677628800000). JavaScript's Date.now() uses milliseconds, while many Unix systems use seconds.
Why do we use Unix timestamps?
Unix timestamps provide a universal, timezone-independent way to represent time. They're easy to store, sort, and calculate with, making them ideal for programming and database applications.
What is the Unix Epoch?
The Unix Epoch is January 1, 1970, 00:00:00 UTC. This date was chosen as the starting point for Unix timestamps and has become the standard reference point for time in computing.
How accurate are the conversions?
Our conversions are highly accurate, using JavaScript's built-in Date object which handles timezone conversions and leap years automatically. All processing happens client-side for privacy.
