Unix Timestamp Converter
Unix timestamp is seconds elapsed since January 1, 1970 (UTC). Current timestamp increases by 1 each second. To convert: multiply days by 86400, hours by 3600, minutes by 60. Example: 1704067200 = January 1, 2024.
Convert Unix timestamps to human-readable dates and vice versa. Live current timestamp display. Supports seconds and milliseconds.

Frequently Asked Questions
- What is a Unix timestamp?
- A Unix timestamp (also called Epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. For example, 1706140800 represents January 25, 2024. It provides a universal, timezone-independent way to represent time in computing.
- Why use Unix timestamps?
- Unix timestamps are timezone-independent (always UTC), easy to store (single integer), simple to compare and calculate differences, and universally supported across programming languages. They avoid timezone conversion bugs and daylight saving time issues common with human-readable dates.
- What is the Year 2038 problem?
- The Year 2038 problem affects systems storing Unix timestamps in signed 32-bit integers. On January 19, 2038, at 03:14:07 UTC, 32-bit timestamps will overflow and wrap to negative values (appearing as 1901). Most modern systems use 64-bit timestamps, which extend to 292 billion years.
- What is the difference between seconds and milliseconds timestamps?
- Standard Unix timestamps count seconds (10 digits, e.g., 1706140800). JavaScript and some APIs use milliseconds (13 digits, e.g., 1706140800000). To convert: milliseconds to seconds, divide by 1000; seconds to milliseconds, multiply by 1000. Our tool handles both formats.
- How do I get the current Unix timestamp?
- In JavaScript: Math.floor(Date.now()/1000) or new Date().getTime()/1000. In Python: import time; time.time(). In Bash: date +%s. In PHP: time(). Our converter shows the current timestamp live and lets you convert between timestamp and human-readable formats.
