Timestamp Converter: Convert Unix Timestamps to Human-Readable Dates
The Timestamp Converter is a free tool for developers and data analysts to convert between Unix timestamps and human-readable dates. Whether you're debugging API responses, analyzing log files, or working with databases, this tool makes timestamp conversions instant and accurate.
Unix timestamps represent the number of seconds (or milliseconds) since January 1, 1970 UTC (the "Unix Epoch"). While efficient for computers, they're unreadable for humans. This converter supports both seconds and milliseconds precision and displays results in your local timezone.
💡 Why Convert Timestamps?
Timestamps are everywhere in development: database records, API responses, JWT tokens, log files, analytics data. Reading "1703001600" as "December 19, 2023" requires either calculation or a tool like this.
This converter handles both formats instantly, showing you the exact date and time in a human-readable format. It also shows the current timestamp for quick reference.
🎯 Typical Use Case:
You're debugging why a user's session expired. The JWT shows exp: 1703001600. Instead of calculating manually, you paste it here and immediately see it's "December 19, 2023 16:00:00".
🔧 Practical Use Cases
🔐 JWT Token Debugging
Check when tokens expire by converting the exp and iat claims.
{"exp": 1703001600} → Dec 19, 2023 16:00:00
📊 Log Analysis
Convert timestamps in log files to understand when events occurred.
[1703001600] ERROR: Connection timeout
🗄️ Database Queries
Generate timestamps for SQL queries or understand stored values.
WHERE created_at > 1703001600
🌐 API Development
Generate test timestamps or verify API response times.
"timestamp": 1703001600000 (milliseconds)
✨ Features
⚡ Real-Time

❓ Frequently Asked Questions (FAQ)
What's the difference between seconds and milliseconds timestamps?
Unix timestamps in seconds have 10 digits (e.g., 1703001600). Timestamps in milliseconds have 13 digits (e.g., 1703001600000). JavaScript's Date.now() returns milliseconds, while many backend systems use seconds.
What is the Unix Epoch?
The Unix Epoch is January 1, 1970 00:00:00 UTC. All Unix timestamps are calculated as the number of seconds (or milliseconds) since this moment. It was chosen as the starting point for Unix time systems.
What is the Year 2038 problem?
32-bit systems storing timestamps as signed integers will overflow on January 19, 2038. Modern systems use 64-bit integers, solving this problem for billions of years. Most current software is already updated.
