Unix Timestamp Converter
Convert epoch time to dates and vice versa. Supports timezones, milliseconds, and batch conversion.
About the Calculator
Unix time (epoch time) is the number of seconds since January 1, 1970 00:00:00 UTC. This converter turns timestamps into human-readable dates and vice versa. Use it when working with APIs, databases, or logs that store times as numbers. It handles seconds, milliseconds, microseconds, and nanoseconds, and shows conversions across common timezones. Use the Unix Timestamp Converter to get a clear result you can act on right away. This calculator is designed to be practical, fast, and easy to use on any device. If you are comparing options, run a few scenarios to see how small changes affect the outcome.

🎉 Fun Facts
- •Unix time started on January 1, 1970 at midnight UTC, chosen when Unix was developed at Bell Labs.
- •The Year 2038 problem: 32-bit systems will overflow at timestamp 2,147,483,647 (Jan 19, 2038). Most modern systems use 64-bit.
- •Unix time ignores leap seconds. Every day is treated as exactly 86,400 seconds.
- •JavaScript uses milliseconds (13 digits), while many APIs use seconds (10 digits). Always check the format.
