# Date into intervals splitter

## World's simplest time tool

With this browser-based application, you can split any calendar period into several smaller calendar intervals. In the options, you can set two calendar dates – the start and end of the original full period, and then enter the number of smaller intervals you want this full period to be divided into. All these intervals can be either the same length or each can have a random length. You can switch between these two modes in the options and also append the precise interval lengths to the output.

Date into intervals splitter tool
What is a date into intervals splitter?

This is a quick online utility for splitting the given date range into multiple continuous ranges. For example, if you have started a new project and you want to divide it into four equal stages, then by entering the start date of the project and the expected completion date of the project in this program, you can create four intervals of equal length for all four development stages. The start and end dates of the range can be entered in the options using the date formats "YYYY-MM-DD hh:mm:ss" or "YYYY-MM-DD". For example, a range with the starting date of "2025-04-01" and the ending date of "2025-08-01" can be divided into two equal intervals "2025-04-01 – 2025-06-01" and "2025-06-01 – 2025-08-01" (here each interval is 61 days long). You can split your date range into an arbitrary number of parts by specifying the part count in the options. In addition to creating intervals of equal length, you can also split a range into random intervals. This can be accomplished by switching to the "Random Lengths Intervals" mode. When this mode is active, the previous example with the range "2025-04-01 – 2025-08-01" can create two random intervals "2025-04-01 – 2025-07-13" (103 days long) and "2025-07-13 – 2025-08-01" (19 days long). Often, you want the random intervals to have some minimal length. For example, instead of 19 random days, you may want the random interval to always be at least 30 days. If you need to enforce such a constraint on the minimum random interval, then you can set this minimum value in the options. You can specify the minimum interval length in days (e.g. "2 days"), hours (e.g. "5 hours"), minutes (e.g. "10 minutes"), and seconds (e.g. "30 seconds"). You can also combine these values and set a minimal interval to something like "2 days 5 hours 15 seconds". Additionally, you can print the length of each generated interval in the output (useful when generating random calendar intervals). Timeabulous!

Split a Year into 12 Equal Parts

In this example, we split the year 2024 into 12 equal parts. As you know, each month has a different number of days, so the 12 equal parts don't fall on the first day of each month. Also, as the year 2024 is the leap year, it has an extra day, and thus when it's divided into 12 equal intervals, each interval gets 30 days and 12 hours.

2024-01-01 00:00:00 – 2024-01-31 12:00:00
2024-01-31 12:00:00 – 2024-03-02 00:00:00

Create Date Intervals of Random Lengths

In this example, we generate 6 random calendar intervals over 100 years – from the year 1950 to 2050. As the intervals are generated randomly, they can be of any length (as small as 1 second and as large as 99+ years).

1950-01-01 00:00:00 – 1963-03-30 11:46:29
1963-03-30 11:46:29 – 1980-08-07 22:34:35

Random Intervals in Summer

In this example, we're planning a trip to 4 destinations. As we couldn't decide how much time we should spend at each destination, we let our algorithm randomly determine the length of each journey. As the summer is pretty long, we also want each trip to last at least 20 days. To do this, we enter the summer range in the options, select the random interval mode, and enter the minimum interval length to be equal to 20 days. As a result, we get 4 intervals printed to the screen, and we additionally print their precise lengths next to each interval as well.

2025-06-01 00:00:00 – 2025-06-23 19:57:40 (22 days, 19 hours, 57 minutes, 40 seconds)
2025-06-23 19:57:40 – 2025-07-18 00:55:45 (24 days, 4 hours, 58 minutes, 5 seconds)
2025-07-18 00:55:45 – 2025-08-10 22:15:47 (23 days, 21 hours, 20 minutes, 2 seconds)
2025-08-10 22:15:47 – 2025-08-31 23:59:59 (21 days, 1 hour, 44 minutes, 12 seconds)
