time into intervals splitter

world's simplest time tool

With this browser-based application, you can split any time period into several smaller time ranges. You can specify the start and end clock time in the options and generate as many stop points in this range as you like. You can create intervals of equal lengths or random lengths. If the intervals are random length, you can also specify the minimum required distance between the random times. Additionally, you can display the duration of each interval on the screen. Created by computer nerds from team Browserling.

What is a time into intervals splitter?

This is a quick online utility for dividing a time interval into several continuous intervals. You can create multiple intervals with the same length or multiple random time slots throughout the day. For example, you can split your working day from 09:00:00 to 17:00:00 into 8 equal parts to complete 8 tasks; or for example, you can create 10 random intervals between 6pm and 9pm for a team game. The start and end time of the full range can be specified in the options using the formats hh:mm:ss, hh:mm, or hh. If the start and end time fields are left empty, then by default, the time range is set to cover the entire day from 00:00:00 to 24:00:00. You can specify the required number of time intervals in the options. If you turn on the equal interval mode, you can split a range 12:00 – 15:00 into three equal ranges and get 12:00 – 13:00, 13:00 – 14:00, and 14:00 – 15:00. Note that the first and last time points of the new smaller intervals are the same as the original interval's start and end values. By switching to the random interval mode, you can get three intervals of any length, for example, 12:00:00 – 12:20:34, 12:20:34 – 13:04:19, and 13:04:19 – 15:00:00. As the randomness algorithm works unpredictably, very short and very long ranges can be created, such as 12:00:00 – 12:00:01, 12:00:01 – 14:59:59, and 14:59:59 - 15:00:00. As you can see, the first range is 1 second long, the second is 2 hours, 59 minutes, and 58 seconds long, and the last one is again 1 second long. To make all ranges more or less the same length, you can specify the minimum interval length. For example, you can make sure the intervals are at least 20 minutes long by entering "20 min" in the minimal interval length option. Similarly, you can make intervals at least "50 sec", "30 min", or "1 hour" long. To make sure the generated time intervals have the lengths you need, you can activate the option to print interval lengths in the output. Timeabulous!

A Continuous Timetable

In this example, we create equal time intervals for a class schedule. We enter the value "12:00:00" for the start of the range option and we enter the value "18:00:00" for the end of the range option. We then split this range into 10 equal time intervals, each 36 minutes long.

12:00:00 – 12:36:00 12:36:00 – 13:12:00 13:12:00 – 13:48:00 13:48:00 – 14:24:00 14:24:00 – 15:00:00 15:00:00 – 15:36:00 15:36:00 – 16:12:00 16:12:00 – 16:48:00 16:48:00 – 17:24:00 17:24:00 – 18:00:00

Random Time Intervals

In this example, we split the day into 12 random time intervals. As the day starts at 00:00:00 and ends at 24:00:00, the initial range is 24 hours long. We don't specify a minimum time interval and allow the intervals to have any length.

00:00:00 – 05:43:49 05:43:49 – 07:16:33 07:16:33 – 07:27:03 07:27:03 – 11:15:27 11:15:27 – 12:34:14 12:34:14 – 15:26:03 15:26:03 – 17:22:44 17:22:44 – 17:55:18 17:55:18 – 21:21:48 21:21:48 – 21:49:31 21:49:31 – 23:28:47 23:28:47 – 00:00:00

Show Interval Durations

In this example, we use the minimal range length option and ask the algorithm to generate 6 random intervals from the range 22:00:00 to 01:30:00 so that each interval is at least 30 minutes long. In the output, we get slightly perturbed intervals with an average length of 30 – 45 minutes. We also print the length of each interval in parentheses.

22:00:00 – 22:37:58 (37 minutes and 58 seconds) 22:37:58 – 23:09:18 (31 minutes and 20 seconds) 23:09:18 – 23:41:50 (32 minutes and 32 seconds) 23:41:50 – 00:22:06 (40 minutes and 16 seconds) 00:22:06 – 00:56:17 (34 minutes and 11 seconds) 00:56:17 – 01:30:00 (33 minutes and 43 seconds)
