About this random time generator
Random times are useful more often than you might think: spreading out reminders or social posts so they do not all land on the hour, picking a surprise meeting slot, scheduling test jobs, filling sample data, or setting challenges in games. This generator picks each time uniformly from the range you choose, so every second, minute, or hour in it is equally likely, using your browser’s secure random generator. Ranges may cross midnight, such as 22:00 to 06:00, and the end time is included. You can show times on a 24-hour or 12-hour clock, sort them, and export them as CSV with the seconds since midnight or as a JSON array.
How to generate random times
- Choose the range. Pick a part of the day, business hours, or a custom range with your own start and end.
- Set the format. Choose how many times, the precision, the clock style, and whether to sort them.
- Press Generate times. Copy or download the list, or switch the export to CSV or JSON.
Frequently asked questions
Can the range cross midnight?
Yes. If the end time is earlier than the start, such as 22:00 to 06:00, the range wraps past midnight, and sorting keeps times in order from the start of the range.
Is the end time included?
Yes. For 09:00 to 17:00 with whole hours, 17:00 itself can be picked, so there are nine possible times.
Can the same time appear twice?
Each time is picked independently, so repeats are possible, especially with hour precision or a short range. Generate again if you need all different times.
What does seconds since midnight mean in the CSV?
It is the time as a single number, from 0 at midnight to 86,399 at 23:59:59, which makes sorting and calculating in spreadsheets easy.
Are the times tied to a time zone?
No. They are plain times of day, so you can read them in whatever time zone your schedule uses.
