How to Use the Timestamp Converter
- 1View the live current Unix timestamp at the top of the page
- 2Enter a Unix timestamp (seconds or milliseconds) to convert it to human-readable formats
- 3Or use the date/time picker to convert a date to a Unix timestamp
- 4Select a timezone from the dropdown to see the date in different regions
- 5Use quick buttons (Now, +1 Hour, +1 Day, +1 Week) for common offsets

Frequently Asked Questions
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. It's a simple, timezone-independent way to represent a point in time, widely used in programming, databases, and APIs.
What's the difference between seconds and milliseconds timestamps?
Unix timestamps in seconds are 10 digits (e.g., 1700000000), while millisecond timestamps are 13 digits (e.g., 1700000000000). JavaScript's Date.now() returns milliseconds, while many APIs and databases use seconds. This tool auto-detects which format you enter.
What is the Year 2038 problem?
The Year 2038 problem affects systems storing Unix timestamps as 32-bit signed integers, which overflow on January 19, 2038. Modern 64-bit systems are unaffected. This tool uses JavaScript's 64-bit floating-point numbers, so it handles dates well beyond 2038.
How does timezone conversion work?
Unix timestamps are always in UTC. When you select a timezone, the tool uses the browser's Intl.DateTimeFormat API to display the equivalent local time in that timezone. The underlying timestamp value doesn't change — only the display format does.
Is my data processed on a server?
No. All conversions happen entirely in your browser using native JavaScript Date and Intl APIs. No data is sent to any server, ensuring complete privacy.
