Random Time Generator

Random time generation comes up more often than you'd expect. Building a scheduling app and need realistic test data? Writing a mystery novel and want authentic-feeling timestamps? Running a classroom lottery where the winner has to guess a randomly picked time? This tool has you covered.

12-hour vs 24-hour format matters depending on your context. If you're testing a UI that shows time to end users in the US, 12-hour format (9:45 AM, 2:30 PM) is more realistic. If you're generating data for a server log, system timestamp, or European-audience application, 24-hour format (09:45, 14:30) is the standard. Both formats are supported here and can be toggled instantly.

Including seconds is useful when you need high-precision timestamps for test data — transaction logs, API response times, event queues. Without seconds, you get cleaner values that work better for user-facing time displays like appointment slots or scheduling grids.

Times are generated with a uniform distribution across all 24 hours, all 60 minutes, and all 60 seconds. Each time value is equally likely, so you'll get a proper spread across the day rather than clustering around certain hours.

Generate in batches of 1, 5, 10, 25, or 50. Results stack up so you can generate multiple rounds without losing previous values. Use "Copy all" to grab the entire list as line-separated text, ready to paste into a spreadsheet, code file, or document. Previous results stay visible until you clear them, so you can generate in rounds and compare.

Everything runs in the browser — no server calls, no stored data, no rate limits. Generate as many times as you need.
