Random calendar date generator
World's simplest time tool
With this browser-based application, you can create a list of random calendar dates. In the options, you can specify the minimum date (starting date) and maximum date (ending date) for the range as well as enter how many dates you want to select from this range. You can choose the date format and composition, and also use custom format calendar templates. Additionally, you can generate unique random calendar dates and specify a date separator character for a custom list. Created by computer nerds from team Browserling.

What is a random calendar date generator?
learn more about this tool
This is a quick online utility for generating random calendar dates. If you need a list of random dates in any format and from any time period, you can quickly get it here. We added multiple options that let you customize the random dates. You can specify the number of dates you need in the output list and adjust the delimiter symbol between them. If you want the dates to be printed in a vertical column, use the delimiter character "\n". If you want to list them separated by commas, specify the comma character "," as the delimiter. By default, the range of generated dates is set to the 21st century, going from "2000-01-01 00:00:00" to "2099-12-31 23:59:59". You can set a new date interval by updating the start and end date options fields. For the randomly generated dates, by default, the output format is "YYYY-MM-DD hh:mm:ss" but you can choose a new format from the predefined list of formats or create a custom format by switching to the custom format mode and entering a date template that contains the abbreviations of date and time components. If the date has a time component (hh:mm:ss), you can choose between a 12-hour or 24-hour time format for it. If the 12-hour format is selected, the clock time component will be formatted with the "am" and "pm" indicators. You can also enable or disable the padding option for all calendar dates. When generating random dates, there's a small chance of generating two identical dates. To make sure that all generated dates are unique, you can disable the "Allow Duplicate Dates" option. Timeabulous!
Random calendar date generator examples
Click to useRandom Calendar Dates From a 40-year Interval
In this example, we create nine random calendar dates in the format YYYY-MM-DD hh:mm:ss. All random dates fall within a 40-year, 4-month, and 4-day interval (specified in the options) from 2020-02-02 to 2060-06-06. We use full padding for all the dates and display them in a vertical column.

Random Days of the Week
In this example, we generate 12 random dates from the year 2030. Each date is unique and contains the abbreviated name of the month and the day of the week. We also switch to a 12-hour time format, so that all clock times have with am/pm indicators.

Random Custom Format Dates
In this example, we create a custom date format and generate 16 random calendar dates. After selecting the custom format mode, we specify the date pattern as "MM.DD.YYYY". Here, "MM" means month number, "DD" means day number, and "YYYY" means the year. We set a large range of a century (one thousand years) and separate all random dates in the output with the em dash symbol.
03.18.1979 — 11.18.1875 — 07.29.1398 — 07.16.1593 — 02.09.1483 — 08.02.1633 — 01.10.1361 — 02.28.1040 — 11.26.1944 — 04.08.1253 — 12.17.1274 — 03.17.1279 — 03.25.1579 — 11.09.1162 — 03.07.1874 — 02.07.1505
