Free Timestamp Converter - Unix Time to Date & Vice Versa
Convert Unix timestamps to human-readable dates and dates to timestamps. Support for multiple timezones and formats.
What is Timestamp Converter?
Our Timestamp Converter helps you convert between Unix timestamps (epoch time) and human-readable dates instantly. Whether you're debugging API responses, working with database records, or analyzing log files, our tool makes timestamp conversion effortless.
Unix timestamps represent time as the number of seconds since January 1, 1970 00:00:00 UTC (the Unix epoch). They're used everywhere in programming: databases store dates as timestamps, APIs return timestamps, and server logs use timestamps. Our tool converts these numbers to readable dates and vice versa.
The tool supports multiple timezone conversions, various date formats (ISO 8601, RFC 2822, custom formats), and both seconds and milliseconds timestamps. You can also get the current timestamp with one click, making it perfect for testing and development.
All conversions happen instantly in your browser. No server requests, no data storage - just fast, private timestamp conversions. Works offline once loaded, perfect for developers working in secure environments or remote locations.

Frequently Asked Questions
Everything you need to know about Timestamp Converter
A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC, not counting leap seconds. It's a universal way to represent time in programming because it's timezone-independent, easy to store (just a number), and simple to compare. Most programming languages and databases use Unix timestamps internally. JavaScript uses milliseconds instead of seconds (multiply by 1000).
10-digit timestamps represent seconds since epoch (standard Unix timestamp), while 13-digit timestamps represent milliseconds. Most Unix systems and programming languages like Python, PHP use seconds. JavaScript uses milliseconds for more precision. Our tool auto-detects which format you're using. To convert between them: seconds × 1000 = milliseconds, or milliseconds ÷ 1000 = seconds.
Unix timestamps are always stored in UTC (timezone-independent), but display depends on timezone. When you convert a timestamp to a date, choose your target timezone. The same timestamp (e.g., 1609459200) shows as "Jan 1, 2021 00:00:00" in UTC but "Dec 31, 2020 19:00:00" in EST. Always store timestamps in UTC in databases, then convert for display based on user's timezone.
Yes! Unix timestamps can represent any date, not just current time. Negative timestamps represent dates before January 1, 1970. For example, -86400 is December 31, 1969. Future dates have large positive timestamps. However, very old dates (before 1902) or far future dates (after 2038 on 32-bit systems) may have limitations depending on your system.
Our tool supports multiple output formats: ISO 8601 (2021-01-01T00:00:00Z), RFC 2822 (Fri, 01 Jan 2021 00:00:00 +0000), human-readable (January 1, 2021 12:00 AM), or custom formats using date patterns. Choose the format that matches your programming language, API requirements, or database schema. Each format has specific use cases - ISO 8601 is best for APIs and JSON.
No! All timestamp conversions happen entirely in your browser using JavaScript. Your timestamps, dates, and conversion history never leave your device or get sent to any server. This makes it completely safe for working with production data, sensitive log files, or confidential database records. The tool works offline once loaded.
