About Timestamp Converter

The Timestamp Converter is an essential tool for developers working with dates and times. It converts Unix timestamps (epoch time) to human-readable dates and vice versa, supporting both seconds and milliseconds formats. Perfect for API development, database queries, and date manipulation tasks.

Use Cases:

  • Converting Unix timestamps from APIs and databases to readable dates
  • Converting dates to timestamps for API requests and queries
  • Debugging timestamp-related issues in applications
  • Understanding JWT token expiration times
  • Working with different timezone formats (UTC, local time)
  • Converting between seconds and milliseconds timestamp formats

Key Features:

  • Bidirectional conversion (timestamp ↔ date)
  • Automatic detection of seconds vs milliseconds
  • Multiple date format outputs (ISO, local, UTC)
  • Date component breakdown (year, month, day, time)
  • Current timestamp display with live updates
  • 100% browser-based - no server processing

Convert Datetime to Unix Timestamp

Converting datetime to unix timestamp is essential for programming and database operations. Our converter supports both directions: datetime to unix timestamp and unix timestamp to datetime. Simply enter your datetime in the date picker or type a date string, and get instant unix timestamp conversion.

Unix timestamps are widely used in programming because they're easy to store, compare, and calculate with. They're timezone-independent, precise, and efficient for databases and APIs. Whether you're working with JavaScript, Python, PHP, or any other language, converting datetime to unix timestamp is a common task.

How to Convert Datetime to Unix Timestamp:

  1. Select 'Date to Timestamp' mode in the converter above
  2. Enter your datetime using the date picker or type a date string (e.g., 2024-01-15 10:30:00)
  3. The tool automatically converts it to unix timestamp in both seconds and milliseconds
  4. Copy the timestamp value you need for your code or database

The converter displays results in multiple formats including ISO format, local time, UTC, and provides both seconds and milliseconds timestamps. This makes it easy to use the timestamp in any programming language or database system.

Frequently Asked Questions

How do I convert a Unix timestamp to a date?

Enter your Unix timestamp (in seconds or milliseconds) in the input field and select 'Timestamp to Date' mode. The tool will automatically convert it and display the date in multiple formats including ISO, local time, UTC, and readable date components.

How do I convert a date to a Unix timestamp?

Select 'Date to Timestamp' mode, enter a date (you can use the date picker or type a date string), and the tool will convert it to Unix timestamp in both seconds and milliseconds format.

What is a Unix timestamp?

A Unix timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970, 00:00:00 UTC (the Unix epoch). It's a common way to represent dates in programming and databases.

Does the tool support both seconds and milliseconds?

Yes! The tool automatically detects whether your timestamp is in seconds (10 digits) or milliseconds (13 digits) and converts accordingly. It also displays both formats in the results.

Is the timestamp converter free to use?

Yes! Our timestamp converter is 100% free with no registration required, no usage limits, and no hidden fees. You can convert as many timestamps as you need for your development work.

What timezone does it use?

The tool displays dates in multiple formats: UTC (Coordinated Universal Time), local time (based on your browser's timezone), and ISO format. You can see all formats in the results.

How do I convert a timestamp from milliseconds to seconds?

If your timestamp is in milliseconds (13 digits), the tool automatically detects and converts it. You can also divide by 1000 manually. The tool displays both seconds and milliseconds in the results.

What is the Unix epoch?

The Unix epoch is January 1, 1970, 00:00:00 UTC. Unix timestamps count the number of seconds (or milliseconds) that have elapsed since this date. It's the standard reference point for timestamps in computing.

Can I convert future dates to timestamps?

Yes! The tool can convert any valid date, past or future, to a Unix timestamp. Simply select 'Date to Timestamp' mode and enter your date using the date picker or by typing a date string.

How accurate are the timestamp conversions?

The conversions are highly accurate and handle leap years, timezone conversions, and daylight saving time correctly. The tool uses JavaScript's Date object which follows international date standards.

What date formats are supported?

The tool accepts various date formats including ISO 8601 (YYYY-MM-DD), standard date strings, and dates from the date picker. It displays results in ISO format, local time, UTC, and provides detailed date components.

How do I convert datetime to unix timestamp?

To convert datetime to unix timestamp, select 'Date to Timestamp' mode, enter your datetime (e.g., 2024-01-15 10:30:00), and the tool will convert it to unix timestamp in both seconds and milliseconds. Unix timestamps count seconds since January 1, 1970, 00:00:00 UTC.
