How the Random Time Generator Works
Enter a start hour and an end hour, choose a minute step, and press the button to draw one time from that window at random. Every result is printed in both 24-hour and 12-hour form, so it copies straight into an alarm or a calendar entry. It fits random spot-check times, study reminders, break slots, and any schedule you would rather not choose yourself.
The window and the minute step
Both hours accept 0 through 23, and the end hour includes that hour all the way through its 59th minute. Setting the end hour to 18 therefore keeps 18:59 in the pool. With the start at 0, the end at 23, and a 1-minute step, all 1,440 times of the day are candidates. A 5-minute step keeps only times whose minute is a multiple of five, and a 30-minute step leaves just :00 and :30. The result reports which step was used and how many candidate times it produced. A start hour later than the end hour, or an hour outside 0 to 23, returns a message instead of a result.
Drawing several at once
Candidate times are shuffled with the Fisher-Yates algorithm and sliced from the front, so a single draw never repeats a time. The picks are sorted from earliest to latest for easier reading. Ten is the maximum per draw, and if fewer candidates exist, only those come out with a note explaining the adjustment. Minutes are always padded to two digits, so nine oh five reads as 09:05.
Frequently Asked Questions
Yes. With the start hour at 0, the end hour at 23, and a 1-minute step, all 1,440 times from 00:00 to 23:59 are candidates.
Only times whose minute is a multiple of that value are candidates. A 5-minute step yields :00, :05, :10 and so on, while a 1-minute step keeps every minute.
Yes. The end hour includes that hour through its 59th minute, so setting 18 keeps everything up to 18:59 in the pool.
