Timestamp Converter
Convert Unix timestamps, dates and times between different formats.
Supports seconds, milliseconds, ISO 8601 and multiple timezones.
About This Timestamp Converter
Kivixa Timestamp Converter is a free online tool that helps you convert Unix timestamps into readable dates and convert dates and times back into Unix timestamp values. Unix timestamps are commonly used in websites, APIs, databases, server logs, programming languages, and software applications to represent dates and times in a consistent format.
Unlike a basic Unix Timestamp Converter Online, Kivixa supports multiple timestamp formats including seconds, milliseconds, microseconds, and nanoseconds. The tool automatically detects the timestamp unit and displays the converted local time, UTC time, ISO 8601 date, relative time, Unix seconds, and Unix milliseconds.
The tool also includes a built-in Timestamp Inspector for understanding unknown timestamp values, a Batch Timestamp Converter for processing multiple timestamps, and a Timestamp Difference Calculator for finding the exact time between two Unix timestamps. These features make it useful for debugging application logs, checking API responses, working with databases, and handling date and time values during development.
For date-based conversion, you can select an actual timezone such as UTC, Asia/Kolkata, America/New_York, or other supported IANA timezones. The selected timezone is used when converting the entered date and time into a Unix timestamp.
Whether you're searching for a Timestamp Converter, Unix Timestamp Converter, Unix Time Converter, Epoch Converter, Timestamp to Date Converter, Date to Timestamp Converter, or Unix Timestamp Generator, Kivixa provides a fast, accurate, free, and privacy-friendly solution that works smoothly on desktop, tablet, and mobile devices.
How to Use the Timestamp Converter
- Enter a Unix timestamp in the Timestamp to Date section. The tool automatically detects whether the value is in seconds, milliseconds, microseconds, or nanoseconds.
- Review the converted result including local time, UTC time, ISO 8601, relative time, Unix seconds, and Unix milliseconds.
- Use the Timestamp Inspector when you want to understand an unknown timestamp and identify its detected unit and corresponding date.
- To convert a date into a timestamp, open Date to Timestamp, select the date and time, and choose the appropriate timezone.
- Use the Batch Converter to paste multiple timestamps, one per line, and convert them together. You can copy the results or export them as a CSV file.
- To find the time between two timestamps, enter the start and end values in the Timestamp Difference Calculator.
- Open Live Timestamp whenever you need the current Unix timestamp in seconds or milliseconds. Use the timezone converter when comparing times across different regions.

Every feature is designed to make working with Unix timestamps easier. Instead of switching between separate timestamp converters, timezone tools, batch converters, and timestamp calculators, Kivixa brings these common date and time utilities together in one simple interface. Whether you're debugging an API response, checking server logs, converting database values, or working with timestamps in your application, you can quickly inspect, convert, compare, and copy timestamp values from a single tool.
Why Use This Timestamp Converter?
Dates and times can become surprisingly confusing when applications work across different programming languages, databases, APIs, servers, and timezones. A value such as 1757836800 may look like a random number, but it actually represents a specific point in time. A reliable Unix Timestamp Converter makes these values easier to understand and verify.
Kivixa goes beyond a basic Timestamp Converter Online by combining timestamp conversion, timestamp inspection, batch processing, timestamp difference calculation, live Unix time, and timezone conversion in one lightweight tool. You can work with seconds, milliseconds, microseconds, and nanoseconds without manually guessing the timestamp unit.
Supports Multiple Timestamp Units
Work with Unix timestamps in seconds, milliseconds, microseconds, and nanoseconds. The converter automatically detects the unit and processes supported timestamp values for you.
Built for Developers
Quickly inspect API responses, database values, server logs, and application timestamps. View ISO 8601, UTC, local time, and Unix representations without additional calculations.
Fast, Secure & Private
Timestamp calculations happen directly in your browser. No account, installation, or server-side processing is required, making the tool fast and convenient for everyday use.
Batch Conversion & Timezone Tools
Convert multiple timestamps at once, export results as CSV, compare timestamps, and work with different timezones from one simple interface.
Final Thoughts
Unix timestamps are an important part of modern software development. They provide a consistent way to represent points in time and are commonly found in APIs, databases, authentication systems, server logs, websites, and backend applications. However, timestamp values are not always easy to read when they appear as long numbers.
Kivixa's Timestamp Converter makes it simple to convert, inspect, compare, and understand Unix timestamps. With support for seconds, milliseconds, microseconds, nanoseconds, timezone-aware date conversion, batch processing, timestamp differences, and live Unix time, you can handle most everyday timestamp tasks without using multiple separate tools.
Whether you're debugging an API, checking a database value, analyzing server logs, testing an application, or simply trying to understand what a Unix timestamp represents, this tool provides the information you need in a clean and easy-to-use interface.

Frequently Asked Questions
Everything you need to know about Unix timestamps and timestamp conversion.
A Unix timestamp is a number that represents a specific point in time by counting the number of seconds that have passed since January 1, 1970, at 00:00:00 UTC. Unix timestamps are widely used in programming, databases, APIs, operating systems, and web applications to store and exchange dates and times consistently.
A timestamp converter is an online tool that converts Unix timestamps into readable dates and converts dates and times back into Unix timestamp values. It makes it easier to understand timestamp values used by websites, APIs, databases, logs, and software applications.
Unix seconds represent time using the number of seconds since January 1, 1970, while Unix milliseconds represent the number of milliseconds since the same starting point. For example, a typical current Unix timestamp in seconds has around 10 digits, while a timestamp in milliseconds usually has around 13 digits.
The Timestamp Inspector is a built-in feature that helps you understand an unknown timestamp. It detects the timestamp unit and displays the original value, Unix seconds, Unix milliseconds, UTC time, ISO 8601 date, and a readable date in one place.
Yes. The Batch Timestamp Converter allows you to paste multiple timestamps, with one timestamp per line. Each value is processed automatically and the detected unit, Unix seconds, ISO date, and conversion status are shown in the results.
Yes. The Timestamp Difference Calculator lets you enter two Unix timestamps and calculates the time between them. The result includes the difference in days, hours, minutes, and seconds along with the total seconds and milliseconds.
Yes. Use the Date to Timestamp section, select a date and time, choose the appropriate timezone, and the tool will generate the corresponding Unix timestamp in seconds and milliseconds along with the ISO 8601 UTC representation.
Yes. When converting a date to a Unix timestamp, the selected timezone determines how the entered local date and time is interpreted. This is useful when working with applications, APIs, databases, and users located in different parts of the world.
