With this browser-based application, you can sort a list of calendar date intervals. You can rearrange the date intervals in order from the earliest to latest, from the latest to earliest, from the shortest to longest, from the longest to shortest, or just mix them up in random order. If any of the intervals are duplicated, then you can find and remove them. Additional options let you display the duration of each interval, customize the date format, remove the clock time part, and adjust the zero padding of date components. Created by computer nerds from team Browserling.
This is a quick online utility for sorting multiple date intervals. You can paste a list of multiple date intervals as the input and get a sorted list of intervals as the output. A valid date interval has two ISO 8601 format dates that are dash separated and look like this: "YYYY-MM-DD - YYYY-MM-DD", where the first date is the starting date and the second date is the ending date. For example, an interval "2022-07-10 - 2022-10-10" has a duration of 3 months. Both dates in an interval must be separated by a dash that's surrounded by spaces " - ". Each date must not contain any additional spaces between the date components and must be formatted exactly like this: "YYYY-MM-DD". The program also accepts a single calendar date "YYYY-MM-DD". For example, a calendar date "2022-10-15" has a duration of 0 days (it's the same as "2022-10-15 - 2022-10-15", which is the same day). Optionally, the dates can also contain a clock time part in the format "YYYY-MM-DD hh:mm:ss". For example, "2022-10-25 12:30:45". As soon as a vertical list of date intervals is loaded into the input field, the program will immediately sort all intervals according to the selected sorting mode. There are five different sorting modes. The first two rearrange the intervals in order from the earliest to latest or vice versa from the latest to earliest. In this case, the sorting algorithm compares the start dates of all intervals and displays them from smallest to largest. The second two modes sort the intervals by their length: from the shortest interval to the longest one or vice versa. In this case, the program finds the time difference between the interval end and start values and then arranges the intervals according to this duration. The last sorting mode is random and it simply shuffles all the intervals in the list and outputs them in random order. Additionally, the program can print the duration of each interval on the screen and remove repeated date intervals from the list (printing only the unique date intervals). Several more extra options can adjust the date format for the sorted intervals, switch the clock time part to 12-hour format or remove the clock time part altogether (if it's present). Finally, you can add or remove the zero padding to the date components. Timeabulous!
In this example, we sort a list of calendar date intervals in order from the earliest to latest. The interval sorting algorithm takes the start dates from each interval, compares them, and arranges the intervals in order from the earliest date to the latest date. We also disable printing the time part of the intervals and make the date format of output intervals have the same format as they were entered in the input.
This example calculates the length of each interval and outputs a sorted list with intervals going from the longest one to the shortest one. If an interval contains only the start date (called a single-point interval), then its length is 0 days and it's the shortest possible interval. The program also displays the duration of each interval in parentheses and removes the repeated intervals that are identical. The intervals are also re-formatted and converted to abbreviated text format without the clock time part and without padding.
In this example, we shuffle a list of date intervals using the random sorting option. All start and end dates in the intervals use the ISO 8601 format "YYYY-MM-DD hh:mm:ss" that includes the time part. In the output, we switch to the North American date format, where the month comes first, followed by a slash-separated day and year: "MM/DD/YYYY hh:mm:ss". We also preserve the time part in the output and convert it to a 12-hour clock format.
You can pass input to this tool via ?input query argument and it will automatically compute output. Here's how to type it in your browser's address bar. Click to try!
