About Date to Unix Timestamp Converter

This free online date and Unix timestamp converter tool allows you to transform between human-readable dates and Unix timestamps instantly. Whether you're a developer working with APIs, databases, or system logs, our bidirectional converter handles both date-to-timestamp and timestamp-to-date conversions seamlessly in your browser. Switch between seconds and milliseconds, choose from 5 different output formats, and convert multiple entries at once.

Why Convert Between Dates and Unix Timestamps?

Unix timestamps (also known as Epoch time or POSIX time) represent time as the number of seconds (or milliseconds) since January 1, 1970 00:00:00 UTC. They're essential for programming, databases, and system administration because they provide a timezone-independent way to store and compare dates. Converting between human-readable dates and timestamps is crucial for debugging logs, working with APIs, scheduling tasks, analyzing data, and synchronizing systems across different timezones.

How to Use This Converter

Converting dates and timestamps is straightforward: choose your conversion direction (Date → Unix or Unix → Date) using the mode toggle at the top. Paste or type your dates or timestamps into the input field (one per line for batch conversion). Select your preferred unit (seconds or milliseconds) and output format if converting timestamps to dates. Click the convert button to get your results instantly. Use the "Now" button to insert the current timestamp, and the swap button to flip the conversion direction with your output.

Key Benefits

• No installation required: Works directly in your browser without any software downloads
• Completely free: No registration, credit card, or hidden fees
• Secure and private: All conversion happens locally - your data never reaches our servers
• Fast processing: Instant conversion with no waiting time
• Bidirectional: Convert Date → Unix or Unix → Date with one click
• Batch conversion: Process multiple dates or timestamps simultaneously
• 5 output formats: ISO 8601 UTC, ISO 8601 Local, UTC string, Locale, and RFC 2822
• Live clock: See current timestamp updating in real-time

Common Use Cases

Developers use timestamp converters for debugging server logs with Unix timestamps, converting API response dates for database storage, scheduling cron jobs and automated tasks, working with JavaScript Date.now() milliseconds, analyzing log files from different systems and timezones. Database administrators convert timestamps for queries and data migration. DevOps engineers troubleshoot deployment timestamps and system events. Data analysts transform timestamps for visualization and reporting. QA testers verify date handling in applications across timezones.

Supported Date Formats

Our converter accepts a wide variety of date input formats including ISO 8601 (2024-01-15T08:00:00Z), RFC 2822 (Mon, 15 Jan 2024 08:00:00 GMT), locale strings (January 15, 2024), natural formats (Jan 15 2024, 1/15/2024), and more. For timestamp-to-date conversion, choose from ISO 8601 UTC, ISO 8601 Local (with timezone offset), UTC string format, locale-specific format, or RFC 2822 format depending on your system requirements.

Technical Features

Our converter handles both Unix seconds (standard) and milliseconds (JavaScript), processes multiple dates or timestamps in batch mode (one per line), displays a live updating clock showing current timestamp, provides accurate timezone conversion, validates input and shows clear error messages, preserves precision for millisecond timestamps, supports dates from 1970 to 2038+ (64-bit timestamps), and includes quick actions like "Now" button, copy, download, and swap functionality for efficient workflow.

Privacy and Security

Unlike online converters that send your data to remote servers, this tool processes everything locally in your browser using JavaScript. Your server logs, database timestamps, deployment times, or any time-sensitive data never leave your computer, making it safe for converting confidential information. No cookies, tracking, or data storage. Perfect for working with production logs, internal system times, or any sensitive temporal data.
