Timestamp Converter
Convert Unix timestamps (seconds) to human-readable dates and vice versa.
Try it with this example
Enter 1709769600 and convert to date. Or pick a date and get its Unix timestamp.
What is this tool?
Unix timestamps—also called epoch time or POSIX time—count seconds since January 1, 1970 at 00:00:00 UTC. Nearly every programming language and database uses them internally. Logs, APIs, and cron jobs often store or display times as numbers. When you see 1709769600 in a log or API response, you need to know what date and time that represents. The Timestamp Converter turns numbers into human-readable dates and dates into numbers, instantly.
Enter a Unix timestamp (seconds since the epoch) and convert it to a date. The tool handles both 10-digit timestamps (seconds) and 13-digit timestamps (milliseconds). If you enter 1709769600, you get a date in 2024. Enter a date and time, and the tool gives you the corresponding timestamp. That's useful when you're writing scripts, building APIs, or debugging: "When does this cron run?" or "What date is 1714521600?"
Databases often store timestamps in UTC. The converter displays times in your local timezone and in UTC so you can compare. When scheduling tasks or setting up APIs, knowing the exact moment a timestamp represents avoids off-by-one errors. Developers use this when constructing Date objects, writing SQL WHERE clauses, or parsing API responses. Support teams use it to translate error logs—"the failure occurred at 1709769600" becomes "March 6, 2024 at 4:00 PM UTC."
Cron expressions use a different format (minute, hour, day, month, weekday), but understanding timestamps helps when debugging scheduled jobs. If a job runs "at 3am," is that server time or UTC? Converting timestamps clarifies that. APIs like Twitter, Stripe, and GitHub return timestamps in their responses; this tool helps you interpret them during development and support.
The tool runs entirely in your browser. No API calls, no server processing. Enter a number or pick a date, and the conversion is immediate. It's one of those utilities you don't need often, but when you do, having it ready saves time. Bookmark it for the next log file or API response that leaves you wondering what time it really was.
