Random Time Generator

By default the generator returns hours and minutes (HH:MM), which gives 1440 possible values across a 24-hour day. You can switch to second-level precision (86,400 values) or even millisecond precision for testing scenarios that need fine granularity. Each level uses uniform rand

How granular are the random times?
By default the generator returns hours and minutes (HH:MM), which gives 1440 possible values across a 24-hour day. You can switch to second-level precision (86,400 values) or even millisecond precision for testing scenarios that need fine granularity. Each level uses uniform random sampling, so every valid time has an equal chance of being selected.
Can I limit the result to working hours?
Yes. Set a start time and end time and the generator only samples within that window. For example, 09:00 to 17:00 will give office-hours times. You can also exclude lunch by generating two separate ranges (09:00-12:00 and 13:00-17:00) and combining the results, since the tool does not natively support skipping a middle gap.
Why would I need a random time?
Common use cases include scheduling unpredictable check-ins for security drills, picking a random meditation or break time, generating test data for time-stamped events, randomizing reminder notifications so users do not anchor on a fixed minute, and picking a fair starting time for a multi-timezone meeting where no one wants to volunteer.
Does it support 12-hour and 24-hour formats?
Yes, you can toggle between 24-hour (military) format and 12-hour AM/PM format. The underlying random number is the same; only the display changes. ISO timestamps and database fields almost always use 24-hour format, while everyday English speakers usually prefer the 12-hour version with AM/PM suffixes.
Can I generate times across midnight?
Yes. If your start time is later than your end time (for example 22:00 to 04:00), the tool treats it as a window that crosses midnight and samples uniformly across the wrapped six-hour span. This is useful for night-shift schedules or generating realistic "late night" event timestamps in test data.
How do I generate a list of random times in order?
Generate the count you need, then sort the output ascending. The tool can do this automatically with the "sort" option. Sorting after sampling does not bias the results; it just rearranges them. If you need times spaced apart by a minimum gap (such as no two within 10 minutes), generate extras and discard those that violate the gap rule.
